Alembic depsgraph: explicitly add ANIMATION -> CACHE dependency

This dependency was removed in fd0bc7e002ced8ffd85e9aa3edcae173dbd13392,
as there already were dependencies ANIMATION -> PARAMETERS and
PARAMETERS -> CACHE, making ANIMATION -> CACHE unnecessary.

Upon subsequent inspection, the ANIMATION -> PARAMETERS dependency was
there due to the fallback behaviour in
`RNANodeQuery::construct_node_identifier()`. Now this is no longer
relied upon, and the required relation is made explicit again.
