Summary:
Pull Request resolved: https://github.com/pytorch/audio/pull/3249

- Put ptr member private so that it's more secure and subclasses won't mess with it
- Remove unused `reset` method
- Do not default construct the managed object
  - Introduce helper function for default allocation.
    (for AVFrame and AVPacket as they are allocated in both reader and writer)
  - for others, allocation logics are moved to where it is used.
- Remove unused `pHWBufferRef` attribute from `StreamWriter`.

This commit refactors the initialization of EncodeProcess.

Interface-wise, the signature of the constructor of EncodeProcess
has made simpler just to take rvalues of its components, and the
initialization of the components have been moved to helper functions.

Implementat-wise, the order that the components are initialized is
revised, and the source of initialization parameters is also revised.

For example, the original implementation first creates AVCodecContext,
and passes it around to create the other components. This relied on
an assumption that parameters AVCodecContext has (such as image size
and sample rate) are same as the source data. This is not always right,
and as we will introduce custom filter graph and allow on-the-fly
transform of rates and dimensions, it will become even less correct.

The new initialization constructs source AVFrame, TensorConverter and
FilterGraph from source attributes. This makes it easy to introduce
on-the-fly transform.
