[PATCH i-g-t 1/8] tests/kms_ccs: Convert int/bool to enum

[Daniel Stone <daniels@xxxxxxxxxxxxx>]

Rather than using TEST_UNCOMPRESSED / TEST_COMPRESSED as alternately
either an int or a bool, change it to a bitfield enum.

This will let us add more parameters later to control framebuffer
generation.
