fix: Fix Video Recording delay and improve startRecording() performance (#2192)

Browse Source 
* fix: Add more logs

* perf: Init audio AVAssetWriter in parallel

* chore: Log Audio Session activation

* perf: Init Audio Session asynchronously

* chore: Log when category changed

* fix: Revert lazy audio initialization

* Update Podfile.lock

* Pass `sourceFormatHint` to video and audio AVAssetWriter

* fix: Remove `sourceFormatHint` from Video Asset Writer

* Use default options for Audio Asset Writer

* Update Podfile.lock

* Revert "Use default options for Audio Asset Writer"

This reverts commit e575a14c5342ddc7f9db557d5e3915328ed9e798.

* Add time logs

* fix: Don't synchronize audio buffers, they are already in sync

* shouldOptimizeForNetworkUse = false

* fix: Only update `latestTimestamp` once video buffer has been written

* perf: Use `AVAssetWriterInput` instead of `AVAssetWriterInputPixelBufferAdaptor`

* fix: Fix Audio not being synchronized with Video

* Remove logs add comments

* Format

* feat: Set `.videoRecording` AVAudioSession mode

* Refactor `startRecording()` a bit

* Format

* chore: Throw error directly instead of double-checking
