Document TFLite Support vs MediaPipe

[Tachi107]

Hi all, could you please consider documenting which parts of tflite-support are to be considered superseded by MediaPipe? It has been mentioned multiple times that MediaPipe is what you are focusing on now (#723 (comment), #880 (comment), #885 (comment), #894 (comment), #917 (comment)), but a lot of existing documentation, like the TFLite Android quickstart, still suggests using the TensorFlow Lite Task Library.

It'd be nice to know if the TFLite Task library is to be considered deprecated, and whether MediaPipe should be used instead.

Thanks!
