drm/xe/rtp: Drop rule matching cases from rtp_to_sr_cases and rtp_cases

The kunit test cases for the RTP framework are currently separated into
three groups:

(1) rtp_rules_cases:
    Those to verify rule matching logic.

(2) rtp_to_sr_cases:
    Those to verify generation of save/restore tables from RTP tables.

(3) rtp_cases
    Those to verify processing of RTP tables without save/restore action
    associated, which are used for OOB workarounds.

Today we have some cases in (2) and (3) that are actually meant to
verify rule matching logic.  Now that we have (1), let's cleanup (2)
and (3) so that they become focused on their main objectives.
