chore(android): improve exoplayer logs (#3780)

* perf: ensure we do not provide callback to native if no callback provided from app

* chore: rework bufferConfig to make it more generic and reduce ReactExoplayerView code size

* chore: improve issue template

* fix(android): avoid video view flickering at playback startup

* fix: improve debuging display and enable it in the sample
