[PATCH i-g-t] tests/kms_setmode: Convert to igt_display atomic API

[Jeevan B <jeevan.b@intel.com>]

Replace legacy drmModeSetCrtc()-based modeset handling with the
igt_display atomic commit API.

Use igt_output/igt_crtc abstractions for connector and pipe handling,
and perform modesets via igt_display_try_commit_atomic() with
ALLOW_MODESET.

Drop legacy resource handling and switch to igt_display_t for
managing outputs and CRTCs. Update connector handling to use
igt_output_t and igt_crtc_connector_valid() for compatibility checks.

Simplify cleanup by using igt_display_reset() instead of manually
unsetting CRTCs.

Remove the TEST_STEALING subtest, as its behavior relies on legacy
drmModeSetCrtc() semantics that do not map to the atomic API.

Update related helpers and data structures accordingly.
