drm/xe/tests/rtp: Add kunit test for whitelist upper bounds

Xe must only add registers to the GT whitelist if they are listed in the
"Software Allowlist" section of the bspec.  These registers have been
carefully reviewed by the architecture/security teams to ensure that
they are safe to whitelist from a security perspective.  The list of
allowed registers changes from platform to platform, and it is not safe
to assume that a register is safe to whitelist on a new platform/IP just
because it was whitelisted on older ones.  This means that whitelist
entries in the driver that used undefined upper bounds
(XE_RTP_END_VERSION_UNDEFINED) for their version ranges should always be
considered illegal since they could potentially open unexpected security
holes on future platforms.  Add a kunit test to scan the whitelist RTP
table and ensure that all entries have well-defined upper bounds on IP
version ranges.
