Collect modules' info to create IDE project file.

- Register a singleton and implement GenerateBuildActions func in java/jdeps.go.
- Declare a interface and a struct to collect info in android/module.go.
- Implement IDEInfo for Library & Import module in java/jdeps.go.
- Implement IDEInfo for Genrule module in genrule/genrule.go.
- Implement IDEInfo for fileGroup module in android/filegroup.go.
- Test codes for jdeps.go in java/jdeps_test.go.

Bug: 111044346

Test: export SOONG_COLLECT_JAVA_DEPS=1;mmm packages/apps/Settings
      out/soong/module_bp_java_deps.json will be generated
