Fix for circular linker dependency with cache code library.

The `bf_pointcache_alembic` code is a separate library, to avoid
muddling up core code with alembic includes and preprocessor defines.
Alembic stuff only belongs strictly into alembic code and can be
disabled cleanly.

The `bf_pointcache` and `bf_pointcache_alembic` libraries had a circular
dependency, because the alembic implementation functions were called
directly. Now there is a "Factory" class to abstract the creation of
concrete implementations for readers and writers.
`bf_pointcache_alembic` defines this factory and is registered
//outside// of the core `bf_pointcache` lib, so there is no linker
circularity.
