a96e277b56 m1n1.utils: Add Constant support to Register 
This allows setting register fields to an expected contant value, e.g.
because they are opcodes for a variable-format register (like a mailbox)

f8110dd409 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.

1d932888f9 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.

9fae977161 m1n1.fw.dcp.ipc: Add SizedArray/SizedBytes to handle data/len pairs 
The serialization always uses fixed-length arrays. These wrappers use a
length argument (possibly coming later in the args) to size the fields
so that the arrays are truncated or padded to the right length as
returned to the user.
