Seungha Yang 53dc1b96e2 d3d11compositor: Reconfigure resource only when output caps is changed

Aleksandr Slobodeniuk e683000573 d3d11videosink: fix race conditions in win32 window 
One race condition is the fact that the window object
can be destroyed while running some routine in the UI
thread (such as resizing). To avoid that situation we make
UI thread hold a reference on the window object while it's
running.
Other probpematic case is when the window handle is reused:
if we stop and start the pipeline very fast,
so the sink creates a new window object that is going to use
the same window handle as the previous one.
And finally the case when the pipeline is stopped immediatelly
right after starting, this one is also handled in this commit.

NOTE: a unit test that reproduces this cases have been added
in the previous commit.

Seungha Yang 95ca40c4ab d3d11screencapturesrc: Use keyed mutex instead of fence 
D3D11 runtime might not support ID3D11Fence, and if so GstD3D11Fence
abstraction will use ID3D11Query instead. However, since the ID3D11Query
requires busy waiting, keyed mutex is better approach.

Célestin Marot 81f121f244 d3d11overlaycompositor: fix texture width and height 
The dimension of the overlay texture directly corresponds to the size of the overlay **buffer** which is given by its video meta.
The dimension at which the overlay should be displayed directly correspond to the overlay `render_width`and `render_height`.

Seungha Yang 04451b108a d3d11videosink: Call ShowWindow() from window thread 
... when rendering on external HWND. ShowWindow() will cause
synchronous message passing to window thread and then can be blocked.
At the same time, window thread can wait for GStreamer thread.
Instead of the synchronous call, queue the task to window message
and performs from the window thread.

Seungha Yang a27c5c81df d3d11videosink: Fix deadlock when parent window is busy 
Deadlock sequence:
* From a streaming thread, d3d11videosink sends synchronous message
  to the parent window, so that internal (child) window can be
  constructed on the parent window's thread
* App thread (parent window thread) is waiting for pipeline's
  state change (to GST_STATE_NULL) but streaming thread is
  blocked and waiting for app thread

To avoid the deadlock, GstD3D11WindowWin32 should send message
to the parent window asynchronously.
