Add java_api_library properties to java_defaults

Context
- Some Java API surfaces have subset relationships (i.e. public API
  surface is a subset of system API surface). Thus, simply listing
  all API files that contributes to hierarchical API surfaces when
  defining java_api_library modules can lead to repetition of code in
  Android.bp files.
- Utilizing java_defaults can resolve this problem by
  grouping java_api_contribution modules by API surfaces, and reduce
  code repetition and enhance readability.

Implementation
- Modify java_api_library module to utilize java_defaults modules.
