Update IndexAMProperty API to sync with YB additions to IndexAmRoutine

- Add YB properties to IndexAMProperty enum:
  - AMPROP_YB_IS_FOR_YB_RELATION
  - AMPROP_YB_IS_COPARTITIONED
  - AMPROP_YB_CAN_UPDATE_TUPLE_INPLACE
- Add corresponding property names to am_propnames array
- Add property handling logic in indexam_property function
- Enable pg_indexam_has_property, pg_index_has_property, and
  pg_index_column_has_property functions to access YB properties

Fixes #22246
