This PR aims to fix #3490

Move logic for initial key system selection (no keysystem selected yet) and handling of key system selection after MPD updates (keysystem has already been selected) to separate functions: _selectInitialKeySystem and _selectWithExistingKeySystem
Reduce mediaInfoArr to the latest mediaInfos for a specific stream id
_selectWithExistingKeySystem is only applied when init data has changed to avoid unnecessary calls to requestMediaKeySystemAccess

…for key system access only if init data has changed.
