[PATCH i-g-t 3/4] tests/kms_atomic: Add solid fill plane subtest

[Jessica Zhang <quic_jesszhan@quicinc.com>]

Add a basic test for solid fill planes.

This test will first commit a single-color framebuffer plane then
a solid fill plane with the same contents. It then validates the solid
fill plane by comparing the resulting CRC with the CRC of the reference
framebuffer commit.
