* fix: performance problem in crashReporter.start() on macOS
This change reduces the duration of crashReporter.start() on Intel macOS
from 622 milliseconds to 257 milliseconds!

posix: Replace DoubleForkAndExec() with ForkAndSpawn()
The DoubleForkAndExec() function was taking over 622 milliseconds to run
on macOS 11 (BigSur) on Intel i5-1038NG7. I did some debugging by adding
some custom traces and found that the fork() syscall is the bottleneck
here, i.e., the first fork() takes around 359 milliseconds and the
nested fork() takes around 263 milliseconds. Replacing the nested fork()
and exec() with posix_spawn() reduces the time consumption to 257
milliseconds!
See https://github.com/libuv/libuv/pull/3064 to know why fork() is so
slow on macOS and why posix_spawn() is a better replacement.
Another point to note is that even base::LaunchProcess() from Chromium
calls posix_spawnp() on macOS -
