Avoid passing around []hiddenAPIModule 

Previously, an []android.Module was converted to an []hiddenAPIModule
that was then used to retrieve boot dex jars. That was ok when
obtaining the dex jar files from source modules for
bootclasspath_fragment but does not work well for other use cases as
it would require doing that conversion in multiple places.

This change pushes the use of hiddenAPIModule down to the methods that
retrieve information from it which makes the methods more flexible and
easier to reuse.
