Generalize the handling of dist tags

Previously in order to make use of dist entries with tag properties it
was necessary for each module type to be modified to store the results
of GenerateTaggedDistFiles(module) in the AndroidMkEntry.DistFiles
property. This change generalizes that mechanism to work across all
module types.

This change does improve the behavior of a couple of tests where
previously a dist with tag property was ignored because tagged dist
files were not available now it is used correctly.

Some module types do not implement OutputFileProducer interface and so
they cannot handle dist with tag properties. This change makes it an
error to attempt to do that. That necessitated adding OutputFiles(tag)
method to customModule in queryview_test.go as some of the tests in
that file used dist entries with tag properties.

Follow up changes will remove the code that was made redundant by this.

Test: m nothing
      m dist sdk - before and after this change, compare result to
      make sure that there are no significant differences.
