Fix (unreported): 'CoInitializeEx' being called without 'CoUninitialize'

Problem introduced in {rB1f223b9a}.

This was possibly causing random crashes in Blender file browser when
compiled with ASAN.

Microsoft documents indicate that any call to `CoInitializeEx` must be
balanced by a corresponding call to `CoUninitialize`.

Geometry Nodes: refactor instances component

The main goal of this refactor is to not store Object/Collection
pointers for every individual instance. Instead instances now
store a handle for the referenced data. The actual Object/Collection
pointers are stored in a new `InstanceReference` class.

This refactor also allows for some better optimizations further down
the line, because one does not have to search through all instances
anymore to find what data is instanced.

Furthermore, this refactor makes it easier to support instancing
`GeometrySet` or any other data that has to be owned by the
`InstancesComponent`.

Fix T86450: Random dark UI elements when redrawing

Resolves occasional glitch/flicker drawing dark buttons in the UI.

Regression in 405a5d3bd7ada5dd5af605b59ba07c7144f144a2
which removed shader unbinding when the batch is drawn.

GPU_shader_bind could run with the sRGB uniform in an unexpected state.

Fix T87905: GPencil modifiers not applied if saved with multiframe

When saving a file in Edit mode with Multiframe enabled, the render did not include the modifiers.

Now the multiframe is not enabled if it's doing a render.

UI: Object Thumbnails Orientation Change

Object orientation for thumbnail creation changed to be slightly
oblique (tilted to one side and from above) to better show shape,
especially when axis-aligned. Camera lens changed to 85 to avoid
distortion of close objects like human heads.

Fix T82824: Draw sensor size with correct alpha

Previously the option in the camera's //Object Data Properties > Viewport Display
> Sensor// would not display the sensor in camera view. This seemed to be caused
by the theme color `TH_VIEW_OVERLAY` having zero set for the alpha channel and
alpha blending being active, resulting in no visible output. Hence
`immUniformThemeColorShade(TH_VIEW_OVERLAY, 100);` is replaced with
`immUniformThemeColorShadeAlpha(TH_VIEW_OVERLAY, 100, 255);`.

GPencil: Fix unreported problem when save file in Curve Edit mode

This is related to T87905

Fix T87554 Exact Boolean performance bug.

There was a quadratic algorithm extracting triangles from a coplanar
cluster. This is now linear.
Also found and fixed a bug in the same area related to the triangulator
added recently: it didn't get the right correspondence between new
edges and original edges.

Cycles: add reference counting to Nodes

This adds a reference count to Nodes which is incremented or decremented
whenever they are added to or removed from a socket, which will help us
track used Nodes throughout the scene graph generically without having to
add an explicit count or flag on specific Node types. This is especially
useful to track Nodes defined through Procedurals out of Cycles' control.

This also modifies the order in which nodes are deleted to ensure that
upon deletion, a Node does not attempt to decrement the reference
count of another Node which was already freed or deleted.

This is not currently used, but will be in the next commit.

Cycles: use reference count to detect used shaders

Shaders are only compiled if they are used by some other Node (Geometry, Light, etc.).
This usage detection is done before updating the Scene, however it fails at detecting
Shaders used by Procedurals not known to Cycles (e.g. ones defined by third party
applications), as Procedurals are only updated after the shaders are compiled.

To remedy this, we now use the Node reference counting mechanism to detect whether a
Shader is used and therefore should be compiled.

This removes `ShaderManager::update_shaders_used` as it is not needed anymore, however,
since it would also update the Shader ids, this is now performed in
`ShaderManager::device_update`, and a new virtual `device_update_specific` method was
added to handle device updates for SVM and OSL.
