Cleanup: Alembic, split source files into reader and writer

This separation between reader and writer code is part of Milesone 2 of
T73363.

In this commit the reader and writer classes are separated into their
own files, any `#include` and `using` statements are cleaned up, and
some separator comments have been removed.

No functional changes.
