a648f0da81 Revert "d3d11device: protect device_lock vs device_new"
This reverts commit 0cb12db96c
(i.e. commit 926d5366b9 on main).

AcquireSRWLockExclusive seems to be acquiring lock in exclusive mode
when the same lock is combined with write lock access.
Reverting the commit because of this is unexpected behavior
and unavoidable OS bug.

0cb12db96c d3d11device: protect device_lock vs device_new
It seems that when D3D11CreateDevice collides in time
with other D3D11 calls, in particular the proccess of
creating a shader, it can corrupt the memory in the driver.
D3D11 spec doesn't seem to require any thread safety from
D3D11CreateDevice. Following MSDN, it is supposed to be called
in the beginning of the proccess, while GStreamer calls it with each
new pipeline.
Such crashes in the driver were frequently reproducing on the
Intel UHD 630 machine.

203f6b00d4 tests/d3d11: add concurrency test for gstd3d11device
We suspect that it's not thread safe to just create and
destroy the device from any thread, particularly because
of D3D11CreateDevice, that is not documented as thread-safe.
While D3D11CreateDevice is usually protected from outside
by the gst_d3d11_ensure_element_data, it still can cross
with the Release() method of another device.

5ac7a21ef0 d3d11: d3d11device: Add gst_d3d11_device_new_{for_adapter_luid,wrapped}
* gst_d3d11_device_new_for_adapter_luid()
  Used for creating D3D11 device for a DXGI adapter (i.e., GPU)
  corresponding to a LUID (Locally Unique Identifier).
  This method can be useful for interop with other APIs such as
  Direct3D12, MediaFoundation, CUDA, etc.
* gst_d3d11_device_new_wrapped()
  Allows creating a new GstD3D11Device object by using already
  configured ID3D11Device. This is conceptually equivalent to
  gst_gl_context_new_wrapped()
