DrawManager: High quality normals for non meshes

This adds high quality normals for non meshes. These include

* Volumetric Object Wireframe
* Metaballs
* Extracted Curves
* Curves in edit mode

This is in preparation to fix a regression in recent AMD
drivers where the `GL_INT_2_10_10_10_REV` data type isn't
working in Polaris cards.

Version: Blender v2.91.1 beta

Fix T79356: Improved icons for MSIX builds

Fixed an issue that was causing the app icon to render with a
'plated' background color in the taskbar and other areas of Windows.

Updated all app icons in Microsoft Store package to match Microsoft's
design recommendations.

Added multiple scales for app icons for high resolution displays.

Added high contrast app icons.

Geometry Nodes: improve Point Distribute node

This greatly simplifies the Point Distribute node. For a poisson disk
distribution, it now uses a simpler dart throwing variant. This results
in a slightly lower quality poisson disk distribution, but it still
fulfills our requirements: have a max density, minimum distance input
and stability while painting the density attribute.

This new implementation has a number of benefits over the old one:
* Much less and more readable code.
* Easier to extend with other distribution algorithms.
* Easier to transfer more attributes to the generated points later on.
* More predictable output when changing the max density and min distance.
* Works in 3d, so no projection on the xy plane is necessary.

This is related to T84640.

Geometry Nodes: cleanup attribute usage

Now that typed attribute wrappers don't need to own the
attribute anymore, many `std::move` calls can be removed.

Depsgraph: Remove redundant copy-on-write operations

This change removes copy-on-write operations from ID nodes which do not
need copy-on-write.

Should be no functional changes, as before the copy-on-write operation
would do nothing for those nodes anyway.

Fix T83411: Crash when using a workspace/layout data path in a driver

Building IDs which are not covered by copy-on-write process was not
implemented, which was causing parameters block not present, and, hence
causing crashes in areas which expected parameters to present.

First part of this change is related on making it so Copy-on-Write is
optional for ID nodes in the dependency graph.

Second part is related on using a generic builder for all ID types
which were not covered by Copy-on-Write before.

The final part is related on making it so build_id() is properly
handling ParticleSettings and Grease Pencil Data. Before they were not
covered there at all, and they need special handling because they do
have own build functions.

Not sure it worth trying to split those parts, as they are related to
each other and are not really possible to be tested standalone. Open
for a second opinion though.

Possible nut-tightening is to re-organize build_id() function so
that every branch does return and have an assert at the end, so that
missing ID type in the switch statement is easier to spot even when
using compilers which do not report missing switch cases.

As for question "why not use default" the answer is: to make it more
explicit and clear what is a decision when adding new ID types. We do
not want to quietly fall-back to a non-copy-on-write case for a newly
added ID types.

Fix: popout windows are sized incorrectly on high DPI screens

There should be a conversion to native pixel size as expected by GHOST at the
window manager level, the dimensions at screen level do not need a conversion.

RNA: allow editing pointer IDProperty values from the UI.

Currently it is not possible to edit bare IDProperty pointer
values which are not explicitly defined through python via
UI fields. This is likely mostly because, unlike numeric values,
pointers aren't marked PROP_EDITABLE by default. However there
are also some bugs in the RNA code that need fixing.

The Geometry Nodes modifier uses bare properties to store
input settings for the node group it wraps, so supporting
Object and Collection sockets requires editable pointers.

This patch marks bare IDProperties editable, and ensures
that changing ID pointers rebuilds the dependency graph.
A type check is needed because an IDPROPERTY PointerPropertyRNA
can actually wrap a group value rather than an ID pointer.

Making pointers editable is not likely to accidentally
affect UI fields that were not intended to be editable,
because a simple `layout.prop` cannot determine which
datablocks to display in the menu and remains read-only.

The PROP_NEVER_UNLINK flag is also removed: it seems it
was added because the edit field that couldn't produce
a menu to set the pointer used to still display the unlink
button, but that seems not to be the case anymore.

Actual support for Object & Collection inputs in the modifier
is added in D10056, which can be used to test this code.

RNA: fix a crash when setting bare IDProperty pointers.

The rna_idproperty_check call should be done before accessing
the prop pointer so that it can detect IDProperty values and
replace them with the actual PointerPropertyRNA object.

Fix T84646: Compositor: In Blender 292 "Set Alpha" node is undefined

Incorrect version code introduced by 9dbea1db66da would not check inside
node groups.

Fix T83300: constant scene refreshing in Cycles with empty volumes

This infinite loop is caused by a conflict between the volume mesh
creation which unintentionally clears the shaders before early exiting
when no grid is found, and the Blender exporter which adds back the
shaders causing us to reupdate as the shaders changed.

To fix this simply preserve the shaders on the Volume node.

(Backported bugfix with additional changes to make it work in 2.91)

Fix: Update normals when switching scene quality

Recent commits also updated normals for metaballs, curves and volumetric
objects. This change tags will tag to generate geometry for these new
types.

Fix T84397: Creating and removing many objects very quickly causes a crash

The root of the issue was caused by the dependency graph using ID pointer
to map evaluated state from old depsgraph to new one upon relations update.
This was failing when IDs were re-allocated rapidly: was possible that
Object ID's evaluated state assigned to Mesh and vice versa.

Now depsgraph uses Session UUID to identify which IDs to restore evaluated
state to. The session UUID is stored in the IDNode, so that id_orig is not
dereferenced on depsgraph update since the ID might be freed.

The root of the issue is identified by Campbell, original patch was done
by Bastien, thanks! Also thanks to Oliver and Ray and everyone else for
testing!

Asset System: Disable Asset Browser as experimental feature

The Asset Browser will be disabled and not available for the 2.92 release. In
alpha/beta builds, there will be an "Asset Browser" option under Preferences >
Experimental, if the developer extras are enabled.
Note that this also disables related UI elements (e.g. "Mark Asset" buttons,
Preferences settings for asset libraries, etc.).

The code is still in master of course, development and testing will continue
there. But there simply needs to be too much polishing and fixing before the
2.92 release, plus there are some design decisions to be reevaluated.

Compositor: "Save as Render" for the file output node

This commit adds the "Save as Render" feature to the file output node,
that allows to disable the application of the configured view transform
and other color management settings on the image. If disable it uses
the standard view transform instead. This feature was originally
suggested in T83842 and is part of the color management improvements
task in T68926. With this feature it is possible to toggle the
application of the color management settings for each input socket
of the File Output node individually.

Fix T84459: Wireframe not displaying with AMD GPU

Issue appears to be caused by AMD graphics driver later than 20.11.1 and
affects older GPUs (Polaris/FIJI cards). Wireframe drawing uses the same
OpenGL data type for storing normals what is known to be faulty.

This patch enabled storing the normals using GPU_COMP_I16. It also
solves the normals drawing in edit mode for vertex and loop normals.
