Cleanup: Use const for context

UI: Category support for instanced panels

This adds support for panel categories to the instanced panel system
used for modifiers and others. The change is pulled from D7997 where
it is needed for FCurve modifiers, but it is unused now.

The change is simple and basically amounts to checking the panel
category where it was overlooked before.

Merge branch 'blender-v2.90-release'

CMake: clarify that the modules are licensed BSD 3-Clause

Many of these are derived from similar modules in the CMake project, which
have this license.

Fixes T79715

Merge branch 'master' into fcurve-modifier-panels

Check category before adding instanced panels to layout

Fix T79736: install_deps.sh failing to download OpenImageIO due to wrong version

Convert assert to BLI_assert

plain assert breaks build

Sculpt: Multires Displacement Eraser Brush

This brush deletes displacement information of the Multires Modifier,
resetting the mesh to the subdivision limit surface.
This can be use to easily delete parts of the sculpt or to fix
reprojection artifacts after applying a shrinkwrap.

Sculpt: Expose Edit Face Set as a tool

Previously the way to use this operations was using the shortcut Ctrl +
W and Ctrl + Alt + W, which was not very discoverable and it was
limiting the amount of options that can be added to the operator.Now the
same functionality of the operator is available as a tool, which will
make easier to add other editing operations and options without adding
more entries to the keymap.

Fix T79706: Delta Transform Animation not working

The object "delta_" rna variables were not added to the depsgraph search
and thus it would not trigger updates of the object during animation
playback.

Fix T79637 Motion blur gives artifacts when changing the camera

DRW_render_set_time is calling RE_engine_frame_set will in turn calls
BKE_scene_camera_switch_update.

To workaround this, we get the original camera object at render init and
get the evaluated version from it after each time change.
