hv_exc: Handle M1RACLES mitigation here due to 12.0 spam
...
macOS 12.0 added a silly ineffective "mitigation" that clears the
register on every context switch. This doesn't actually mitigate
anything, but it does make this sysreg trap performance-critical,
so we have to move its handling into the C side.

Add command categories to reduce command clutter
...
Based on a suggestion from Ludwig Schubert it now uses the inspect class
to generate signatures of the functions for the help messages and
the qualified names which is a big improvement.
Also greatly reduced the clutter by putting the class functions into seperate
categories based on their class name. Now the top level help fits on one
page making it much more readable.
