Remove trimmed api versions file

The trimmed api versions file was used to remove updatable apis from
the lint database. This non-updatable lint database was used with
modules that compile against module-lib or system-server sdks.

However, now we have proper module-lib and system-server lint sdk
databases, that don't have the updatable apis inherently, and we
can remove the api versions trimmer.
