AlembicProcedural: add a socket for the objects

cleanup, format

add support for reading face sets

split logic for reading points and triangles into separate functions

tag attributes as modified, and remove any stale normal data

Merge branch 'master' into cycles_procedural_api

temporarily disable TLAS refitting as it fails when we refit curves

alembic: add hair data to the cache

remove partial support for motion blur

This would need persistent data for final renders, or at least a way to
tell which frames to load.

only use procedural for viewport renders

alembic: remove logic to reload data if already consummed

Simply copy the arrays while waiting for support for reference counting
on the arrays.

cleanup, remove comment

format

cleanup, encapsulate ProceduralManager

cleanup, includes

make sure code compiles without alembic

alembic: check that we indeed have animated transformations
