c3ba77ce16 hv_exc: Handle SYS_IMP_APL_CYC_OVRD in the fast path 
m1n1 now uses this for SMP, and due to wfi FIQ leakage from the HV
timer this gets spammed thousands of times per second. Handle it in
the HV directly.

eb466796d8 fw.dcp: Add some stubs needed for modesetting 
This isn't enough to set the video mode yet but it gets us further. I
think allocate_memory/map_buf/powerOnDART need real implementations,
otherwise setting a video mode crashes the DCP in an APIODMA interrupt
handler, whatever that is.

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.

1a95a9fc17 Shell: do not access properties on startup 
Change the way the shell finds methods to add to the locals on startup: the
methods are queried on the object’s class, rather than the object itself. This
allows detecting if an object’s member is a property and ignore it, rather than
accessing the property.

Attributes whose name starts by ‘_’ are also now ignored, which avoids
importing private methods or Python magic methods in the shell namespace.

Fixes spurious accesses to ProxyUtils’s SIMD properties (b, h, etc) on shell
startup, which caused a ProxyCommandError if m1n1 is not recent enough.

d61bf13cb0 hv: shadow perf monitor IRQ mode and state 
The development Mac OS kernel panics if the PMCR0 sysreg is in an
unexpected state. To avoid that the hypervisor needs to shadow the
interrupt mode and interrupt active flag after it mask the PM FIQ.
Mac OS reads and writes frequently from PMCR0 and PMC 0/1 so handling
in m1n1 is preferred over Python.

3d1747466b Add an option to disable checksumming if possible 
* Introduce feature flags which allows the proxy and m1n1 to determine which
features they have in common.
* Add a feature flag that disables checksumming (by replacing checksums with
constant values) for the data packets exchanged by REQ_MEMREAD, REQ_MEMWRITE
and REQ_EVENT. The feature is enabled if m1n1 supports it; checksumming is kept
enabled for UART communication.
* To ensure no packet loss when checksumming is disabled, an extra sentinel
value is added after the exchanged data for memory read/write operations.
