12532cc8bb mediafoundation: Use core dispatcher of current view instead of main view
Main view might be hidden depending on application's view tree.
In that case, ICoreApplication object doesn't return get_MainView() method

Note that nothing about this behavior was documented by Microsoft
https://docs.microsoft.com/en-us/uwp/api/windows.applicationmodel.core.coreapplication.mainview

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)
