Annotate dependency tags for dependencies of installed files

Relands Ic22603a5c0718b5a21686672a7471f952b4d1017 with a minor
change to track libc++ dependencies for python hosts and after
a fix to an internal genrule that depended on transitively
installed java libraries (ag/13068670).

Soong currently assumes that installed files should depend on
installed files of all transitive dependencies, which results
in extra installed file dependencies through genrules, static
libs, etc.

Annotate dependency tags for dependencies for which the
installed files are necessary such as shared libraries
and JNI libraries.

This avoids extra installed files, and is also a first step
towards genrules using their own copy of tools instead of
the installed copy.
