Add a few subtests that check that lossless compressed render targets
are properly displayed. Also test a few error conditions.

Hi,

this has been tested with Ville's branch at:

https://github.com/vsyrjala/linux/tree/fb_format_dedup_2_ccs

The test was based on Ville's one at:

https://github.com/vsyrjala/intel-gpu-tools/tree/ccs_test_3

Regards,

Tomeu
