avcodec: Add MediaFoundation encoder wrapper

Browse Source 
This contains encoder wrappers for H264, HEVC, AAC, AC3 and MP3.

This is based on top of an original patch by wm4
<nfxjfg@googlemail.com>. The original patch supported both encoding
and decoding, but this patch only includes encoding.

The patch contains further changes by Paweł Wegner
<pawel.wegner95@gmail.com> (primarily for splitting out the encoding
parts of the original patch) and further cleanup, build compatibility
fixes and tweaks for use with Qualcomm encoders by Martin Storsjö.

@section MediaFoundation
This provides wrappers to encoders (both audio and video) in the
MediaFoundation framework. It can access both SW and HW encoders.
Video encoders can take input in either of nv12 or yuv420p form
(some encoders support both, some support only either - in practice,
nv12 is the safer choice, especially among HW encoders).
@section mpeg2
MPEG-2 video encoder.
