Adds support for the 3rd USB-C port on 2021 Macbook Pros.
Currently up to 8 USB-C ports are supported which should be sufficient
for expected future devices.
Tested on Macbook Pro 14" and Mac Mini.

Restore the interrupt masks on chainload or HV guest start. The
interrupt mask is not restored on the USB-C port used by the hypervisor.
This prevents an interrupt storm in the guest when the other USB-C port
is exposed to the guest. Both tps6598x share unfortunately an interrupt
line.

This allows to bringup the USB PHY and the HPM for the
payload without having to initialize the CDC ACM driver
at the same time.

Next stage boots now exit back to main() after replying to the proxy
command, allowing shutdown functions to be called. Introduces a new
P_VECTOR proxy op, distinct from P_CALL. The Python side is reworked
to remain compatible with older versions that do not support this.
