tp: add inputmethod parsing

- Extend WinscopeModule to parse inputmethod messages:
    - InputMethodClients
    - InputMethodManagerService
    - InputMethodService
- Populate tables:
    __intrinsic_inputmethod_clients
    __intrinsic_inputmethod_manager_service
    __intrinsic_inputmethod_service
- Add winscope.sql to stdlib to access instrinsic tables
