Stop requiring apex_available on java_library members of sdks

Previously, adding java_library to an sdk required that the names of
any APEXes that transitively compiled against it were added to its
apex_available property. This change removes that requirement.

Also corrects the dependency path in the TestApexAvailable_IndirectDep
error which previously passed through "shared from static" static
dependency tags even though those are explicitly NOT followed when
checking apex_available settings.
