Add methods to parse resources without assets

- Add ParsedAndroidResources to wrap AndroidResources and resource parsing
  output.
- Implement parse() method in AndroidResources, and support for it elsewhere
- Move some supporting methods to the right place (setting up an aapt2 sdk for
  tests goes to the base test rule, and creating a dummy DataBinding zip goes
  to the DataBinding class).
- Tests for new parse() method, including support for getting a test
  RuleContext instance
