Spreadsheet: breadcrumbs and node pinning

This introduces a context path to the spreadsheet editor, which contains
information about what data is shown in the spreadsheet. The context
path (breadcrumbs) can reference a specific node in a node group
hierarchy. During object evaluation, the geometry nodes modifier checks
what data is currently requested by visible spreadsheets and stores
the corresponding geometry sets separately for later access.

The context path can be updated by the user explicitely, by clicking
on the new icon in the header of nodes. Under some circumstances,
the context path is updated automatically based on Blender's context.

This patch also consolidates the "Node" and "Final" object evaluation
mode to just "Evaluated". Based on the current context path, either
the final geometry set of an object will be displayed, or the data at
a specific node.

The new preview icon in geometry nodes now behaves more like
a toggle. It can be clicked again to clear the context path in an
open spreadsheet editor.

Previously, only an object could be pinned in the spreadsheet editor.
Now it is possible to pin the entire context path. That allows two
different spreadsheets to display geometry data from two different
nodes.

The breadcrumbs in the spreadsheet header can be collapsed by
clicking on the arrow icons. It's not ideal but works well for now.
This might be changed again, if we get a data set region on the left.

commit prior to merge

Last attempt at fixing boundary brush for now. Unassigned boundary
verts now get bend data from their neighbors. Still isn't quite
satisfactory but better then before.

Fix T70286: Dissolve vertices/edges creates duplicate face

* Fix crash in boundary sculpt tool
* For some reason boundary tool sometimes fails to match verts to
boundary verts. It now simply freezes them in place if that happens

USD Import: comment out unused parameters.

USD import: set material viewport display props.

Added logic to set the Blender material's viewport display
diffuse color, roughness and metallic properties from
the corresponding USD preview surface inputs.

EEVEE: Split shading passes to eevee_shading.cc

Commit current code state

EEVEE: Refactor: Split implementation to .cc file

This also wrap GPUFrameBuffer & GPUTexture inside eevee:Framebuffer
and eevee:Texture to improve managment.

Another cleanup was to put all members of `Instance` public to
avoid much complexity in accessing the data with modules
dependencies.

Also split velocity View related data to `class Velocity` and
rename previous `Velocity` to `VelocityModule`

USD import: fixed deprecated function warning.

Replaced call to deprecated UsdShadeConnectableAPI::IsShader()
to fix warning.

Cleanup: Use std::unique_ptr for spline vector

CMake/deps: Remove CPP11 option for OpenImageIO

This flag is obsolete. In its current state (missing -D) it also
results in a CMake unknown argument error on macOS.

Geometry Nodes: Realize instances when applying modifiers

The fact that geometry from instnances isn't realized when applying
a nodes modifier can be very confusing, especially for new users.
Nodes themselves realize geometry instances implicitly whenever they
need to. We also currently make instances real and convert points to
mesh when a modifier is added after the nodes modifier. With this
commit, we simply do the same thing when applying the modifier.

There are a few downsides though:
- This can be an extremely heavy operations in some cases where
geometry nodes is used to instance heavy geometry.
- We will still have the issues with materials, since instances use
materials from their original objects, but real geometry uses
materials from the modifier object.

It was decided to live with the potential performance downsides
for now, the idea is the upsides of the change are more important,
and people making complicated setups will be more likely to know not
to apply the modifier. In the future there could be a warning if it's
necessary though.
