[igt-dev] [i-g-t, v3] tests/kms_cursor_crc: skip pipe on invalid connector in cursor size test

[Dnyaneshwar Bhadane <dnyaneshwar.bhadane@intel.com>]

Only the valid pipe connector combination reach to the igt commit.
Cursor max-size test will not affect existing flow as only skip
for invalid connector.
For cursor-dpms and cursor-suspend not require to check require_cursor_size
becuase the cursor height and width used from drm capablities.

--v3
- Added for_each_pipe_valid_connector() to check for valid connection.
- initialize pipe with default 0/PIPE_A suggestion from Petri.
