Summary:
* Remove MKL and NumPy from Conda build env
* Remove `caffe2::mkl` dependency from `torch_cpu`, which introduced unnecessary and undesided dependency on Intel mac.

TorchAudio does not use BLAS libraries directly, thus all the mentions to MKL should be removed from the codebase.
However, this was causing an issue on Intel mac. It turned out that `torch_cpu` target is pulling `caffe2::mkl` dependency, and the linker on macOS keeps library dependency even if no symbol from that library is used. This stray mkl dependency should be fixed on core side, but also we can modify the target temporarily and remove them.

Also we don't need NumPy on build/run time, so that is removed as well.

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.
