[PATCH i-g-t v3 0/4] tests/intel/xe_eudebug_online: Introduce read/write pagefault tests

[Gwan-gyeong Mun <gwan-gyeong.mun@intel.com>]

Add a pagefault read/write test case so that the xe_eudebug_online test can
validate the invalid access pagefault scenario that the eu thread can cause.

For these tests, use the newly introduced DRM_XE_EUDEBUG_EVENT_PAGEFAULT 
event and struct drm_xe_eudebug_event_pagefault.

The added test cases are shown below.
	xe_eudebug_online@pagefault-read
	xe_eudebug_online@pagefault-write

changes in v2:
    Fix the function name to be more clear. (Andrzej, Christoph)
    Refactor of output attention bits on pagefault event handling (Andrzej)
    Remove / update redudant code (Andrzej, Christoph)
    Use igt_container_of() macro (Andrzej, Christoph)

changes in v3:
    Make block write/read to 1 word (d32) from 4 words(d32 x 4) (Andrzej)
    Update the function name (Andrzej)
    Drop not needed code (Andrzej)
    Integration to handle pagefault scenario in eu_attention_resume_trigger() callback. (Christoph)
