drm-tests/plane_test: add support for high-bit depth RGBx formats
This CL adds support for 30bpp RGBx formats (XR30, XB30, AR30, AB30).
These formats have to be written one word at a time (and not one
byte as the others), so I had to add a bit of code in draw_color().
BUG=b:183760490
TEST=/usr/bin/plane_test --format XR30 --size 600x600 on volteer
(and also the other variations and some other formats to verify
no regressions introduced).
