Summary:
This commit introduces support for multiple FFmpeg versions for OSS binary distributions.

Currently torchaudio only works with FFmpeg 4. This is inconvenient from installing to runtime linking.
This commit allows to pick FFmpeg 4, 5 or 6 at runtime, instead of just looking for v4.

The way it works is that we compile the FFmpeg extension three times with different FFmpeg and ship them.
At runtime, we look for libavutil of specific version and when one is found, load the corresponding FFmpeg extension.
The order of preference is 6, 5, then 4.

To make the build process simple and reproducible, we use pre-built binaries of FFmpeg during the build.
They are LGPL and downloaded from S3 at build time, instead of building every time.

The use of pre-built binaries as scaffolding limits the system that can build torchaudio, so it also introduces
single FFmpeg version support mode. setting FFMPEG_ROOT during the build will change the way binaries are built
so that it will only support one specific version of FFmpeg.

Summary:
Pull Request resolved: https://github.com/pytorch/audio/pull/3348

 The pull request adds a CTC-based forced alignment function that supports both CPU and CUDA deviced. The function takes the CTC emissions and target labels as inputs and generates the corresponding labels for each frame.

Merge utility binding

This commit updates the utility binding, so that we can use `is_module_available()`
for checking the existence of extension modules.

To ensure the existence of module, this commit migrates the binding of utility functions
to PyBind11.

Going forward, we should use TorchBind for ops that we want to support TorchScript,
otherwise default to PyBind11. (PyBind has advantage of not copying strings.)

Summary:
This commit makes the following changes to the C++ library organization
- Move sox-related feature implementations from `libtorchaudio` to `libtorchaudio_sox`.
- Remove C++ implementation of `is_sox_available` and `is_ffmpeg_available` as it is now sufficient to check the existence of `libtorchaudio_sox` and `libtorchaudio_ffmpeg` to check the availability. This makes `libtorchaudio_sox` and `libtorchaudio_ffmpeg` independent from `libtorchaudio`.
- Move PyBind11-based bindings (`_torchaudio_sox`, `_torchaudio_ffmpeg`) into `torchaudio.lib` so that the built library structure is less cluttered.

Background:
Originally, when the `libsox` was the only C++ extension and `libtorchaudio` was supposed to contain all the C++ code.
The things are different now. We have a bunch of C++ extensions and we need to make the code/build structure more modular.

The new `libtorchaudio_sox` contains the implementations and `_torchaudio_sox` contains the PyBin11-based bindings.
