Based on https://developer.android.com/reference/android/media/MediaCodec#using-an-output-surface, frame dropping behaviour depends on the target SDK version. After this change transformer will only use MediaFormat#KEY_ALLOW_FRAME_DROP if both the target and system SDK version are at least 29 and default to its pre 29 behaviour where each decoder output frame must be processed before a new one is rendered to prevent frame dropping otherwise. Also remove deprecated Transformer.Builder constructor without a context and the context setter. PiperOrigin-RevId: 453971097 (cherry picked from commit a105d033a7d44b8c3afb0e8134ad65f624caf256)
