Initialize default components lazily in ExoPlayer.Builder to avoid redundant component instantiations, useful in cases where apps overwrite default components with ExoPlayer.Builder setters. The fields in ExoPlayer.Builder are wrapped in a Supplier (rather than just making then nullable and initializing them in ExoPlayer.Builder.build()) so that we maintain the proguarding properties of this class. The exception is ExoPlayer.Builder.AnalyticsCollector which became nullable and is initialized in ExoPlayer.Builder.build() in order to use any Clock that has been set separately with ExoPlayer.Builder.setClock(). #minor-release PiperOrigin-RevId: 406345976
