filter: add helpers to check for supported/active operation.

Add a couple of helper functions:
- gst_vaapi_filter_has_operation(): checks whether the VA driver
  advertises support for the supplied operation ;
- gst_vaapi_filter_use_operation(): checks whether the supplied
  operation was already enabled to its non-default value.
