This adds IsExceptionNonfatalResource() and its test, and uses it in
crashpad_handler. When non-fatal resource exceptions are encountered, no
crash report is generated. crashpad_handler swallows these exceptions.
Alternatively, it could allow them to be sent to the system’s host-level
resource exception handler, normally com.apple.ReportCrash.root, which
would allow them to be processed in the same way as when Crashpad is not
in use. I’m not sure which option is better. I chose to swallow them
because there doesn’t appear to be much value in letting
com.apple.ReportCrash.root and spindump look at them.
This also moves ExcCrashRecoverOriginalException() to the new file as a
sibling of IsExceptionNonfatalResource(). This provides better
organization.

These two exception types use all 64 bits of the code[0] field. The
ExceptionSnapshot was unprepared to stuff this into a 32-bit field. To
resolve the discrepancy, the more-significant data is taken from the
high 32 bits of code[0]. No information is lost because the full code[0]
is made available as part of the Codes() vector.
