827d6fe73d avcodec/encode: restructure the core encoding code
This commit follows the same logic as 061a0c14bb, but for the encode API: The
new public encoding API will no longer be a wrapper around the old deprecated
one, and the internal API used by the encoders now consists of a single
receive_packet() callback that pulls frames as required.

6c33a230e4 mfenc: Avoid including codecapi.h, fix building in UWP mode with clang
Including codecapi.h and uuids.h in UWP mode doesn't define all defines
properly, ending up with constructs that MSVC silently tolerates, but
that clang errors out on, like this:
    DEFINE_GUIDEX(CODECAPI_AVEncCommonFormatConstraint);

Just avoid including codecapi.h completely and hardcode the last few
enum values we use from there. We already use local versions of most
enums from there, due to older mingw-w64 headers being incomplete.

869f655e2e mfenc: Remove an unused include
This might have been used originally for the decoder parts of
the MediaFoundation wrapper, which aren't merged yet.

c116c127f9 mfenc: Fall back to avctx->time_base if avctx->framerate isn't set
The framerate field is the one users are supposed to set, but not
all users might be setting it, so it might be good to fall back
time_base in that case.

050b72ab5e avcodec: Add MediaFoundation encoder wrapper
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.
