Prevent frequent overlay swapchain recreation in Windows

When there is a new swapchain size request, don't recreate a new swapchain
immediately. Instead, use the previous swapchain size until the the new size
has been requested for 30 frames. Then create a new swapchain with the new size.
We can achieve the same onscreen video size by adding this size delta to the
transform matrix calculation.

Use ResizeBuffers instead of recreating swap chains on resize

This CL implements changing size, format, and flags for both root
surface and video by calling ResizeBuffers.  This is the recommended
method for resizing, and doesn't seem to be prone to flashing, and other
issues that require waiting for all commands to finish.  However, the
implementation has a fallback to recreating swap chain if ResizeBuffers
fails, or when it can't be used e.g. for changing alpha blending mode.

This seems fast enough to not need the resize after 30 frames
workaround which is removed in this CL.

This CL also includes cleanup of the root surface code so that it's not
unnecessarily recreated on any change.

Also, add a histogram to track resize failures and update the swap chain
creation result histogram to emit an HRESULT error code so that we don't
have to look at DumpWithCrashing dumps to figure that out.
