a43d6f6cd9 mfvideosrc: Enable WinRT capture impl. for desktop target
... if target OS version was specified as Windows 10.
When enabled, desktop application can select target capture
implementation between WinRT and Win32
via GST_USE_MF_WINRT_CAPTURE environment
(e,g., GST_USE_MF_WINRT_CAPTURE=1 for WinRT impl.).
Default is Win32 implementation in case of desktop target.

8d7f537782 mediafoundation: Drop IMFCaptureEngine implementation
It was introduced for later use of its enhanced feature over IMFSourceReader
such as taking photo with video preview, audio/video capturing at
the same time, etc. But currently it's not our use case, and it would
be maintenance burden.

cee619486a mediafoundation: Add support for AAC encoding
Add MediaFoundation AAC encoder element.

Before Windows 10, mono and stereo channels were supported audio channels
configuration by AAC encoder MFT. However, on Windows 10,
5.1 channels support was introduced.

To expose correct range of support format by this element
whatever the OS version is, this element will enumerate
all the supported format by the AAC encoder MFT
and then will configure sink/src templates while plugin init.

c4cb51c63d mediafoundation: Add support video capture on UWP app
New video capture implementation using WinRT Media APIs for UWP app.
Due to the strict permission policy of UWP, device enumeration and
open should be done via new WinRT APIs and to get permission from users,
it will invoke permission dialog on UI.
Strictly saying, this implementation is not a part of MediaFoundation
but structurally it's very similar to MediaFoundation API.
So we can avoid some code duplication by adding this implementation
into MediaFoundation plugin.

This implementation requires UniversalApiContract version >= 6.0
which is part of Windows 10 version 1803 (Redstone 4)

eece89042a mediafoundation: Introduce Microsoft Media Foundation plugin
The Microsoft Media Foundation (MF) is the successor of DirectShow.
This commit includes two kinds of video capture implementation,
one uses IMFSourceReader interface which is available since Windows Vista
and the other is based on IMFCaptureEngine interface which is available
since Windows 8.
Note that this new video source element cannot be used in UWP app
for now, since device activation using those APIs are not allowed by MS.
