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.

502aea3969 mfvideosrc: Add a new property for ICoreDispatcher setting 
Since the commit c29c71ae9d,
device activation method will be called from an internal thread.

A problem is that, CoreApplication::GetCurrentView()
method will return nullptr if it was called from non-UI thread,
and as a result, currently implemented method for accessing ICoreDispatcher
will not work in any case. There seems to be no robust way for
accessing ICoreDispatcher other then setting it by user.

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.
