Performance test: CPU overhead while scrolling table of images

### Problem Statement

Goal is to find out CPU overhead of Performance instrumentation of our SDK. The benchmark should be comparable to the [one we have for Android](https://github.com/getsentry/sentry-java/tree/main/sentry-android-integration-tests/sentry-uitest-android-benchmark): scroll through a table consisting of generated images. Also, Android uses p90 averaged across 6 real devices, if possible we want the same but also p50 average in addition to p90
