* Chore: Formatting and cleanup

* Feat: Extraction of exoplayer from MediaPlayerRV + optimisation

- removed all exoplayer imports
- optimised the code to fold methods
- removed recundant checks
- rect is reused
- stop and release methods called appropriately
- todo in activity

* Feat: Fields optimised

- fields made final where possible

* Chore: Used lambda

* Chore: Used lambda

* Feat(SDK-3780): Removed redundant ovrrride

* Feat(SDK-3780): Runtime check for video lib

- exoplayer is deprecated but we do not force migration

* Chore(SDK-3780): Compilation errors fixed

- changes interface signature so corrected the impl

* Feat(SDK-3780): Video library check

- uses media3 if available
- used exoplayer in other cases

* Feat(SDK-3780): Video library check -> Interstitial inapp

- uses media3 if available
- used exoplayer in other cases

* Chore(SDK-3780): optimise find view call

* Chore(SDK-3780): annotate with unstable+static access correctness

* Chore(SDK-3780): unused anno removed

* Feat(SDK-3780): CTInAppNativeInterstitialFragment code cleanup

- moves full screen and normal view layout params in handles
- sets them correctly as needed

* Task(SDK-3894): Fixes init of mediaplayer

- corrects initialisation after removal

* Chore(SDK-3894): code simplified

* Feat(SDK-3780): removes progress bar correctly
