drm/xe/guc: Bump minimum required GuC version to v70.29.2

Browse Source 
The VF API version for this release is 1.13.4.

Bumping the minimum required GuC version just before force-probe
removal allows us to set a baseline for what API features are expected
to be available. I.e., at this point there is no need for any version
checking in the code before using a feature. Of course, if/when the
API is extended in future GuC releases, those new features will need
API version checks in the code.

Bump the recommended GuC versions to match.

Also add numerical comparison helpers to simplify the version number
checks.

v2: Reword commit message and make comparison helpers GuC specific -
