Consolidate alembic export options into a struct

Having 15+ args gets unmanageable.

Fix over-allocation of exported normals.

Avoid calling BKE_object_material_slot_remove.

Only draw the caches' keyframes for the objects in the current scene.

Use case-sensitive str comparison.

Pre-allocate UVs array.

Simplify material creation and assignment.

Use regular include guards

Fix for library cache paths not using library as relative basis

Also rename BKE_cachefile_load -> reload since load is typically use to load a new datablock from a path.

Fix compiling after recent cleanup

Fix typo in comment.

Avoid updating the whole scene when updating cache file dependencies.

This is only effective when enabling the new dependency graph, for the
old depsgraph, we still update the whole scene.

Depsgraph: add relations between cache files and transform cache
constraints.

Make use of the SubD reader.

Implement granular data reading.

This adds a new flag to the ImportSettings to tell what data is to be
read (verts, faces, uvs and mcols currently) to be speed data reading up
a bit. Eventually this coul also be exposed in the modifier's UI.
