[PATCH i-g-t 0/6] tests/kms_pipe_crc_basic: add mst suspend-resume test

[Kunal Joshi <kunal1.joshi@intel.com>]

This patch series introduces MST suspend-resume test to kms_pipe_crc_basic.


While at it add framework for general resource cleanup infrastructure.
The cleanup framework addresses the problem of leaked resources (framebuffers,
pipe CRCs, file descriptors) when tests exit early via igt_require(), igt_skip(),
or igt_assert() failures. By registering resources with the cleanup framework,
tests can ensure proper cleanup on all exit paths without manual handling.

The MST test validates that CRC values remain stable across suspend/resume cycles
for all possible subsets of MST outputs connected to a single MST hub.
