[PATCH 2/2] tests/intel/kms_flip_scaled_crc: Add support for RGB16161616_64B compressed formats

[Melanie Lobo]

MTL supports RGB FP16 format which is a binary floating-point computer
number format that occupies 16 bits in computer memory. In this test
platform shall render compression in display engine to receive
RGB FP16 compressed formats.

This was tested with kernel patch,
