MSVS is strict on header and would not allow `std::runtime_error`
without `<stdexcept>`.

Also this commit removes the stray `"libavutil/frame.h"`,
inserted by IDE, which I missed.

Summary:
Currently, macOS CI jobs install `pkg-config` and `wget` with `brew`.
This is problematic as brew takes a long time with auto-update, and disabling the auto-update is not an ideal solution.
Conda also distributes these packages, so switching to conda.

Example issues with brew installation.
https://app.circleci.com/pipelines/github/pytorch/audio/7825/workflows/53965bcf-6ddf-4e42-ad52-83fd1bbab717

This commit removes the use of `brew` by
1. Replacing the use of `wget` with `curl` (pre-installed in most distro)
2. Install `pkg-condig` from conda.
    Note: All the macOS jobs, including binary build jobs, uses conda. Using `pkg-config` from Conda makes it easy to discover the packages installed from conda. (like `ffmpeg` in https://github.com/pytorch/audio/issues/2122)
3. Add `pkg-config` to conda build-time dependency
4. Make sure that the availability of `pkg-config` is explicitly checked when `sox` is being configured. (otherwise, it will fail at somewhere in the middle of build process with somewhat unintuitve error message)

Summary:
This PR adds `BUILD_FFMPEG` switch to torchaudio build process so that features related to ffmpeg are built.
The flag is false by default, so no CI jobs or development flow are affected.

This is because handling the dependencies around ffmpeg is a bit tricky.
Currently, the CMake file uses `pkg-config` to find an ffmpeg installation in the system.
This works fine for both conda-based installation and system-managed installation (like `apt`).

In subsequent PRs, I will find a solution that works for local development and binary distributions.

Summary:
### Change list

* Split the documentation of prototypes
* Add a new API reference section dedicated for prototypes.
* Hide the signature of KenLMLexiconDecoder constructor. (cc carolineechen )
  * https://489516-90321822-gh.circle-artifacts.com/0/docs/prototype.ctc_decoder.html#torchaudio.prototype.ctc_decoder.KenLMLexiconDecoder
* Hide the signature of RNNT constructor. (cc hwangjeff )
  * https://489516-90321822-gh.circle-artifacts.com/0/docs/prototype.rnnt.html#torchaudio.prototype.RNNT
* Tweak CTC tutorial
  * Replace hyperlinks to API reference with backlinks
  * Add `progress=False` to download

### Follow-up

RNNT decoder and CTC decode returns their own `Hypothesis` classes. When I tried to add Hypothesis of CTC decode to the documentation, the build process complains that it's ambiguous.
I think the Hypothesis classes can be put inside of each decoder. (if TorchScript supports it) or make the name different, but in that case the interface of each Hypothesis has to be generic enough.

- Add `num_classes` argument to `hubert_pretrain_base` factory function because the base model has two iterations of training, the first iteration the `num_cluster` is 100, in the second iteration `num_cluster` is 500.
- The model takes `waveforms`, `labels`, and `lengths` as inputs
- The model generates the last layer of transformer embedding, `logit_m`, `logit_u` as the outputs.
