[PATCH i-g-t 4/4] tests/kms_atomic: Add subtest for solid fill cursor planes

[Jessica Zhang <quic_jesszhan@quicinc.com>]

Add a subtest for testing solid fill cursor planes.

This test will commit a solid fill cursor plane on top of a normal
framebuffer primary plane and compare the resulting CRC with the CRC
value of a framebuffer cursor and primary plane of the same contents.
