qsv: Check d3d shared resource tier using D3D11 API
...
We can check the tier using d3d11 API. Thus, don't need to
create d3d12 device

d3d11device: Add device-removed-reason property
...
In addition to device removed status monitoring in gst_d3d11_result()
method, if ID3D11Device4 interface is available,
an event handle will be used for device removed status update.
And "device-removed" signal is removed since applications can monitor
the device removed status via gobject notify

d3d11device: raise 'device-removed' signal on DXGI_ERROR_DEVICE_REMOVED
...
When this error gets caught the GstD3D11Device object raises the new
"device-removed" signal. This allows to handle the error from outside:
stop the playback, re-create the player, replace the catched GstContext by
the new one.

d3d11converter: Add support for HLSL precompile and bytecode caching
...
Precompile pixel shaders for simple conversion path
(without gamma/primaries conversion) in case of MSVC build.
Even if runtime compile is required (cross-compiled or complex conversion
path), do it only once and reuse the compiled bytecode.
This precompile/caching can save about 95% of time taken by
gst_d3d11_converter_new() call.

Compile HLSL at build time in case of MSVC, and use it if device
supports shader model 5. Also cache/reuse pixel shader and vertex
shader objects.
