[igt-dev] [PATCH i-g-t 4/4] tests/kms_rotation_crc: create generic reflection tests

["Maíra Canal" <mcanal@igalia.com>]

Currently, kms_rotation_crc doesn't have any tests for the reflect-x and
reflect-y properties. Therefore, add generic reflection tests for the
primary and overlay planes. Note that this tests should skip on i915
devices, as i915 devices use reflect-x together with specific modifiers.
