Justin Cohen 30b2f4ba38 ios: Add crashpad_uptime_ns crash key to iOS reports. 
This CL introduces a new crash key 'crashpad_uptime_ns' that records the
number of nanoseconds between when Crashpad was initialized and when a
snapshot is generated.

Crashpad minidumps record the MDRawMiscInfo process_create_time using a
sysctl(KERN_PROC).kp_proc.p_starttime. This time is used to display the
'uptime' of a process.  However, iOS 15 and later has a feature that
'prewarms' the app to reduce the amount of time the user waits before
the app is usable. This mean crashes that may happen immediately on
startup would appear to happen minutes or hours after process creation
time.

While initial implementations of prewarming would include some parts of
main, since iOS16 prewarming is complete before main, and therefore
before Crashpad is typically initialized.
