mach_exc is necessary because libSystem doesn’t contain this at all. exc
is necessary too, however: the copy in libSystem relies on the server

Additionally, some Crashpad code wants to call internal validation
(“check”) routines that are not normally accessible to outside callers
via the copy of exc in libSystem, but they are made accessible here by
processing mig’s output in this Python script.

This also adds MachErrorMessage(), a test-only function that’s a
dependency of TaskMemory’s test, and related test-only error message
functions.
