75f6f79e57 mfvideosrc: Fix for negative MF stride

whether memory layout is top-down or bottom-up manner. Note that
negative stride is allowed only for RGB, system memory.

1d6cdbdc90 mediafoundation: Fix resource leak 
IMFActivate would hold its internal objects unless user call ShutdownObject(),
even if we release the IMFActivate. Here internal objects may
include Direct3D objects, such as texture, device handle for example.

20d9283e3d mfvideosrc: Use only the first video stream per device 
Non-first video stream might not be working with current
implementation. It could be non-video (e.g., photo source) and then
ReadSample() might be blocked forever.

47bbc997f8 mfvideosrc: Set timestamp on buffer when it's captured 
Capture the timestamp immediately when new frame is arrived,
instead of doing that on ::create() method. There would be
time gap between captured time and outputting time.

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.

1a68da54b6 mfvideosrc: Add support for jpeg on Win32 application 
Enable reading jpeg data from webcam if it's supported.
Note that this would be enabled only for Win32.
For UWP, we need to research more about how to support jpeg.

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.
