[PATCH 2/2] tests/intel/kms_flip_scaled_crc: Add tests for FP16 XRGB16161616_64B compressed format

[Melanie Lobo]

MTL supports XRGB16161616_64B 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
XRGB16161616_64B compressed formats.

This IGT test was tested with kernel patch,
