chore: add a TRACE call for `crash_reporter::Start()` (#34268)

chore: add a TRACE call for crash_reporter::Start()

Initializing the crashReporter takes around 620 milliseconds on Intel
macOS. I have sent a CL to crashpad to partially fix the performance
issue in
https://chromium-review.googlesource.com/c/crashpad/crashpad/+/3641386.
It would be beneficial to log the performance impact of this function in
the traces in case this slows down in the future.
