Fix T84710: Instances with only mesh edges or vertices are invisible

Wire-only meshes have a special case in the overlay drawing to give
the wire shader a special color (which avoids the lines being dashed,
somehow). The fast path for duplis didn't have that special case.

Fix: Add tooltip translation marker to disabled hints

This was overlooked, as it seems there's no way for these strings to be
translated currently. Generally it's not that clear whether `N_` or
`TIP_` should be used in this case, but `TIP_` seems more consistent.
To avoid the cost of the translation lookup when the UI text isn't
necessary, we could allow the disabled hint argument to be optional.

Cleanup: Rename curve struct fields

These existing names were unhelpful at best, actively confusing at
worst. This patch renames them to be consistent with the terms
used to refer to the values in the UI.
- `width` -> `offset`
- `ext1` -> `extrude`
- `ext2` -> `bevel_radius`

Fix T92268: Group input and output nodes have inconsistent padding

The group output node did not have the same size padding as the group
input, leading to the node looking different and actually being smaller.

UI: Fix scaling of HSV cursor when zooming

The small circle used to choose the hue/saturation and value in the
color widget was drawn with a fixed screen space size. Now scale the
circle used as cursor in the color widget based on the zoom. This
could have been part of a9642f8d6130 but the implementation is
different.

Based on a fix provided by Erik Abrahamsson

Cleanup: FIx build with USD after recent refactor

rB218360a89217f4e8321319035bf4d9ff97fb2658 missed a couple renames in USD code paths.

Fix T93410: Crash hiding a region from Python used by a popover

Close all active buttons when hiding a region as this can be called
from Python a popover is open from that region.

Failure to do this causes the popover to read from the freed button.

Also rename UI_screen_free_active_but to
UI_screen_free_active_but_highlight since it only frees highlighted
buttons.

Cleanup: spelling in comments

Fix T93555: crash when muting nodes with multiple internal links

The crash happened because I was incorrectly and inconsistently assuming
that a socket is part of at most one internal link. However, this is not the case.
In geometry nodes, an input socket can be internally linked to multiple
output sockets. In the general case, an output could also be linked to multiple
input sockets, even though we don't have that in Blender yet.

Cleanup: Readfile: Remove deprecated `BLO_library_link_copypaste`.

Rewrite of ID paste code in rB3f08488244c0 made this function useless,
ID pasting is now handled by the BKE_blendfile_link_append module too.

Blendread: Remove all instantiation logic from `BLO_library_link_` code.

Instantiation is now fully handled by BKE_blendfile_link_append module.

Note that this also allows removal of the `BLO_LIBLINK_NEEDS_ID_TAG_DOIT`
flag.

Part of T91414: Unify link/append between WM operators and BPY context
manager API, and cleanup usages of `BKE_library_make_local`.

Cleanup: move public doc-strings into headers for 'blenloader'

Cleanup: clarify material copying for hair and pointclouds

No functional change, just more clear this way it comes from src.

Cycles: fix bugs in point and spot light multiple importance sampling

* Spot lights are now handled as disks aligned with the direction of the
spotlight instead of view aligned disks.

* Point light is now handled separately from the spot light, to fix a case
where multiple lights are intersected in a row. Before the origin of the
ray was the previously intersected light and not the origin of the initial
ray traced from the last surface/volume interaction.

This makes both strategies in multiple importance sampling converge to the same
result. It changes the render results in some scenes, for example the junkshop
scene where there are large point lights overlapping scene geometry and each
other.

Cleanup: compiler warning

Cleanup: Move node_shader_util.c to C++

This will allow using a function I've declared in a C++ header.

Fix errors in user preferences after 2.8 hack removal

How to reproduce it:
* Open User Preferences.
* Got to Add-ons tab.

Issue introduced on d723e331f155

Reported via chat by Pedro Alcaide (povmaniac).

Cleanup: Use int8 type rather than char for buffer

Indicates that this is just a buffer with an element size of 8 bit, not
a displayable/printable string buffer.

Fix T92561: unstable particle distribution with Alembic files

When enabling or disabling a Mesh Sequence Cache modifier of an Object
with a hair particle system, the hair would switch positions. This is
caused because original coordinates in Blender are expected to be
normalized, and toggling the modifier would cause the usage of different
orco layers: one that is normalized, and the other which isn't.

This bug exposes a few related issues:
- if the Alembic file did not have orco data,
`MOD_deform_mesh_eval_get`, used by the particle system modifier, would
add an orco layer without normalization
- `MOD_deform_mesh_eval_get` would also ignore the presence of an orco
layer (e.g. one that could have been read from Alembic)
- if the Alembic file did have orco data, the data would be read
unnormalized

To fix those various issues, original coordinates are normalized when
read from Alembic and unnormalized when written to Alembic; and a new
utility function `BKE_mesh_orco_ensure` is added to add a normalized
orco layer if none exists on the mesh already, this function derives
from the code used in the particle system.
