Some more minor cleanups.

Add an assert to BKE_icon_changed() that we are actually dealing with ID icon.

Otherwise, ID->obj is an opaque pointer, wrong usage here could lead to
a vast amount of bad things.

Fix T54310: Assert when enable Brush custom icon.

We had a mix of two issues here actually:
* First, Brush are currently using their own sauce for custom previews,
this is not great, but moving them to use common ImagePreview system of
IDs is a low-priority TODO. For now, they should totally ignore their
own ImagePreview.
* Second, BKE_icon_changed() would systematically create a PreviewImage
for ID types supporting it, which does not really makes sense, this
function is merely here to 'tag' previews as outdated. Actual creation
of previews is deferred to later, when we actually need them.

Cleanup: naming and const parameter.

Depsgraph: Support colored addresses in debug prints

Enabled with --debug-depsgraph-pretty, only works with ANSI terminals.

Thanks Bastien for review!

Add Truecolor ANSI console constants

They are used to start and end colored output in console.
Use with care, it is up to you to check that console actually
supports Truecolor ANSII.

In thew future we can extend this to other consoles and platforms.

Hash: Add utility function to convert address to rgb values

Some magic hashing, will become handy to make debug messages
easier to follow.

Depsgraph: Move evaluation debug prints to depsgraph

This way we can easily control format and keep it consistent.

And also possibly do other trickery, like coloring addresses!

GWN: Uncomment a (now) usefull assert

Eevee: Add warning comment about ubo/texture persistence.

Clay: Small cleanup.

Use persistent binds for the texture and UBOs.
Remove use of stencil.

DRW: Fix/refactor UBO & Texture binding.

Previous approach was not clear enough and caused problems.
UBOs were taking slots and not release them after a shading group even
if this UBO was only for this Shading Group (notably the nodetree ubo,
since we now share the same GPUShader for identical trees).

So I choose to have a better defined approach:
- Standard texture and ubo calls are assured to be valid for the shgrp
they are called from.
- (new) Persistent texture and ubo calls are assured to be valid accross
shgrps unless the shader changes.

The standards calls are still valids for the next shgrp but are not assured
to be so if this new shgrp binds a new texture.

This enables some optimisations by not adding redundant texture and ubo
binds.

Cleanup: doxy sections for editmesh files.

Cleanup: move mesh mirror functions to own file

Code cleanup: fix various compiler warnings on clang/macOS.

Fix T54326: Import Alembic stuck in edit mode

Switch to object mode before doing the import.
