3e807d6686 dart: shutdown to bypass mode 
This allows payloads to use DMA for anything that's not PCIe
even without a DART driver. It also restores the DART registers
the state the were left by iBoot.

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.
