Calculate frame delay, slow+frozen frames inside SentryFrameMetricsCollector

[markushi]

Do it in one place, so we can later use it for both the AndroidProfiler as well as txns.

📜 Description

Mainly moved some logic from AndroidProfiler to SentryFrameMetricsAggregator.
Added some logic to calculate the frame delay, as well as exposing frame start/end times.

💡 Motivation and Context

Partly fixes #3099

💚 How did you test it?

Added unit tests.
