Mesh Selection: Move Selection ID Context Utilities to ED_view3d.

This patch does not bring functional changes, but it is a good change if we want to use these utilities in areas other than those using BMesh (eg painting editors).

This is also a step to replace `ED_view3d_select_id_validate`. That function erroneously checks `V3D_INVALID_BACKBUF` which causes it to update unnecessarily.

Docs: minor improvements to --app-template help text

Draw into OpenGL offscreen context in the DirectX window.

The window doesn't show anything of course. However we draw (at least I
assume it does) as regular, just into a window offscreen context.

A valid 3D view is created in the window. It's not visible but you see
cursor changes as you move over the window. So handling works.

Cleanup: sort structs

Cleanup: minor adjustments to --help text formatting

- Single quote args so they show with string literals in the manual.
- Improve the description of animation playback mode.

OpenVDB: Added backwards compatibility with Tangent 2.78 builds.

(Disabled) code to open a DirectX window with the VR session

The window immediately crashes, hence keeping it disabled for now.

Not sure how much of this I'll leave in, for now this is mainly for
testing DirectX compatibility.

Outliner Visibility: Add Invisible filter

This adds an object invisible filter to the outliner to only show hidden
or disabled objects in the outliner. In large scenes, it is often
difficult to locate hidden objects in the outliner to show them again.
This invisible filter makes it easier.

Outliner: Refine synced selection

Any selection event that uses ED_object_base_select will now
mark the outliners as being dirty. When an outliner draws and is
dirty with synced selection enabled, it will sync its selection
state with the view layer.

More work still needs to be done. This may not be the best way
to implement it (selections from scripts won't be tracked). Also,
selection from the outliner isn't perfect.

Fix T61768 Eevee Offscreen rendering

The issue was caused by a bad usage of GPUOffscreen.

The Framebuffer was created using a window framebuffer and used
in a viewport callback when another GPUContext was bound.

This change allows up to 3 framebuffers per GPUOffscreen.

Most common case will be using 2 framebuffers (one for init and
one for drawing) but in the case of more (bad usage) it will just
degrade performance a bit.

Cloth: accurately find UVs for the edges

Earlier, the mesh would keep splitting at the seams of the UV islands because the distance would be so large. This is now fixed, it correctly finds the UVs of the corresponding edge that match the world space positions as well.

Fix T59275: generated texture coordinates don't stick to mesh for shape keys

No need for this optimization in Eevee anymore, instead the modifier stack will
only compute CD_ORCO when needed.

Fix part of T63595: generated texture coordinates don't stick to deforming mesh

Always compute CD_ORCO undeformed coordinates now for rendering, same as before.
There is still a refresh issue to be fixed, when switching from solid to textured
mode in the viewport.

Computing such undeformed coordinates can be expensive and is not actually needed
if the mesh is only using e.g. UV maps. This was the same in 2.79, at least now we
are skipping the computation when there are no deforming mdifiers on the mesh.

Mesh: don't compute CD_ORCO layer when there are no deforming modifiers

This saves memory and evaluation time for simple static meshes with e.g. a
subdivision surface modifier. If no CD_ORCO layer exists then we assume the
actual vertex coordinates are equal to the original undeformed coordinates.

T65783: UI Inconsistency with Grease Pencil icons in Properties and Outliner

Fixed Properties and tab icons

Fix compile errors with older MSVC/Win-SDK versions

Reported by @LazyDodo, thanks!

Fix T65669 Bones in Envelope Display break apart after selecting bone

This was because the VAOs were not updated if an instance batch was
reusing a VBO containing instances attributes which was reinitialized.

Now we ensure the Batch will reconfigure the VAOs if the VBO is 0.

Fix T65109: Object deleted when removed from the RigidBodyWorld collection.

While user should never do that, it appears many end up using a 'view
layer' instancing collection as RBW collection, and even worse, have
objects in that unique collection.

Therefore, when removing RB simulation from an object, which among other
things has to remove it from the RBW collection, it would fully delete
the object from the blend file.

This fix merely checks the usercount of RB-removed object, and if it is
at 1 (which means object was in a single collection), it adds it to the
scene's master collection first.
