Sculpt: Elastic deform type for Snake Hook

This adds deformation types to snake hook and the elastic deformation
type. This mode deforms the mesh using a kelvinlet instead of applying
the displacement directly inside the brush radius, which is great for
stylized shapes sketching.

Changes in rake rotation when using elastic are too strong when set
to 1, so I'll add a nicer way to support rake rotations with smoother
transitions in the future.

Cleanup: Remove unused c popup menu for text editor

This code hase been usused for 10 years and the right click menu is now

Fix T82242: creating particle influence textures does not set up DEG
relation immediately

Texture and ParticleSettings have a DEG relation, but
`DEG_relations_tag_update` was not called when the texture changed.
This lead to no updates when e.g. texture size changes, relation only
went into full effect after save/reload or adding/removing keyframes.

Two places were additional relation tagging is needed:
- ParticleSettings `active_texture` changes
- ParticleSettingsTextureSlot (basically any TextureSlots') texture
changes

UI: Update theme to match Shader nodes category color with socket color

The change to match socket color and category was already done, but it was missing
versioning code to update the theme on load.

Fixes T83500 (already closed as invalid, but this would solve the non-matching colors)

Fix T83581: "Only local" ambient occlusion option causes error on OptiX 2.92

The SVM AO node calls "scene_intersect_local" with a NULL pointer for the intersection
information, which caused a crash with OptiX since it was not checking for this case and
always dereferencing this pointer. This fixes that by checking whether any hit information
was requested first (like is done in the BVH2 intersection routines).

Cleanup: various clang tidy fixes

Geometry Nodes: simplify supporting different input socket types for attributes

This is a non-functional change. The functionality introduced in this commit
is not used in master yet. It is used by nodes that are being developed in
other branches though.

Fix T83575: GPencil: VFX Blur is not disabled when samples are zero

Before the number of samples was not checked, only the pixel size.

Fix T83588: Crash with Shrink/Fatten and Offset Even

`t->keymap` can be `NULL`.

Bug introduced in rBc822f66bb83

Fix T83460: Regression in snap for measure tool

Now the gizmo is drawn only when the eventstate located in
`wm->winactive->eventstate` has not changed.

So it doesn't matter if it's "selected" or not.

This commit also removes the use of the private header "wm.h"

Degraded AMD 20.11.3 driver to limited support.

Workaround for Access Violation startup crash on deprecated Radeon GPUs on Windows

This is a workaround for T80804.

There's a startup crash that happens on 2.91.0 on Windows, an `EXCEPTION_ACCESS_VIOLATION`
on `atio6axx.dll`. It is triggered by `glClear` on the `detect_mip_render_workaround`
function. The workaround moves the function after the device/driver workaround section and
sets the flag to the affected one to avoid running the check.

It is deprecated hardware that has not meet the minimum requirements since 2.79, but is
still usable and this extends its usability a bit before the cards are finally blacklisted.
