Signal::Usr is handled with mach after 260623@main

rdar://109117815
Reviewed by Justin Michaud.
260623@main made a change to move the handling of
`JS_SHELL_WAIT_FOR_SIGUSR2_TO_EXIT` after
JSC options parsing, which enables signal handing using mach by default.
`Signal::Usr` should
never be handled using mach, and when we attempt this we hit a release
assertion in `toMachMask()`
causing JSC to crash when collecting vmmaps from a remote device. This patch
fixes this by moving
where this signal handler is added back before mach exception handling is
enabled.
