[PATCH i-g-t v4 4/5] tests/xe-ccs: Add tests which exercise small to large blit sizes

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

Testing block-copy for 512 x 512 x 32bpp is not enough to verify
blit is working for different (small) and not always aligned
resolutions. Add 'increment' subtests which checks blits from
small (1x1) to large (512x512) resolutions.

To avoid too long execution resolution increment equals 15x15 pixels.
