drm/amd/display: add CRC IRQ handler KUnit coverage

Browse source

[WHAT]
Expose amdgpu_dm_crtc_handle_crc_irq() for KUnit and add tests for the
incomplete-CRTC early returns, the disabled-source exit, the initial
two-frame skip window, the DPRX post-skip exit, and the failed
dc_stream_get_crc() path that stops before delivering a DRM CRC entry.

These tests reuse the fake DC fixture introduced with the CRC configure
coverage.
