libquery: add optional handling of 'UI' ID pointers.

Handling those through different ways /might/ be needed sometimes, but
in most case this is just a nest of issues, since you can easily forget
to take them into account.

Note that this should be a 'non-functional' change, as this new behavior
is not used anywhere yet.

OCIO: Style fixes

Volumes: browse VDB files from add menu, auto detect sequences, drag & drop

Cleanup: split image sequence detection into own file, and make it reusable

GPencil: Remove unused drawing code for interpolate operator

Volumes: add global volume grid cache

This is used for sharing grids between multiple volume datablocks with the
same filepath, and sharing grids between original and copy-on-write datablocks
created by the depsgraph.

Volumes: use principled volume by default in volume object materials

This is mostly straightforward, but required some refactoring in Cycles to
ensure that the default volume material does not always turn on the volume
feature for GPU rendering.

GPencil: Remove old drawing from Interpolate operator

Now the drawing is done using the normal drawing engine and not the old drawing code.
