Add filegroup modules to module_bp_java_deps.json

This adds all filegroup modules to java_deps.json, since java modules
can have filegroups in their srcs via :<filegroup>

One possible optimization here could be to filter out filegroups that do
not contain .java files when creating module_bp_java_deps.json. This CL
does not do that since the increase in .json file is not significant. In
aosp/main, it increases from ~40MB to ~50MB.

Test: verified that `mime.types.minimized` exists in
module_bp_java_deps.json
