Cleanup: DRW: Remove unused functions

DRW: Change Procedural function to use a GPUBatch

This is in order to have VAO handled by thoses batches instead of using a
common VAO. Even if the VAO has no importance in these case using a batch
will help when transitioning to Vulkan.

Eevee: Replace DRW_shgroup_empty_tri_batch_create by procedural calls

Mesh Batch Cache: Fix use of uninitialized variable

DRW: Make Instance count not a pointer

Goal is still to simplify the draw manager.

Cleanup: Eevee: Make planar downsampling not use instance drawing

Cleanup: DRW: Remove pointers to materials

GPU: Move Material index to nodetree evaluation

This removes the need to pass the Material* all over the place in the draw
manager. Cleanup comming right after.

DRW: Remove ModelViewMatrix and ModelViewMatrixInverse

GPU: Remove ModelViewMatrix and ModelViewMatrixInverse usage

Fix T64588: some new theme preferences not saving

Fix T64339: Crash with UV sculpt after undo

Keymap: add option for tilde key preference

Since the view menu is redundant for people with a numpad,
add a preference for it to switch between gizmos instead.

Preferences: file menu item to temporarily load factory settings

It's common to load factory settings as a test without wanting to
overwrite your own settings on exit.

Preferences: set dirty flag when dragging

Fix property update setting dirty flag

Fix missing preference dirty tagging

Tagging dirty was failing for UI scale, line width, hinting & others.

Checking for an update function means all update functions
need to tag preferences as dirty.

Since this check was added to prevent the active section marking the
preferences as dirty, only exclude this property.

UI: grey out 'Revert' when preferences aren't dirty

Fix T63802: textured lights not working with OSL

Fix T64561: wrong colorspace for Cycles displacement nodes
