tools/amd_hdmi_compliance: Test 4K video modes with YUV encoding

From: Stylon Wang <[email protected]>

HDMI 2.0 compliance tests needs 4K modes with YUV encoding. This test selects 4K modes based on specified VIC.

v2:
- rename to amd_hdmi_compliance
- replace fprintf with igt_info/warn
- use EXIT_SUCCESS/FAILURE in exit()
