Description

onResume isn't correct according to https://developer.android.com/topic/performance/vitals/launch-time#cold

Potentially we should also change when we start measuring app start time (first class load) https://github.com/square/papa/blob/26f21379a8efb14b292c1db5188d4a3be6a48872/papa/src/main/java/papa/internal/Perfs.kt#L300-L359

Relates to #2177 and getsentry/sentry-cocoa#2840.
