f52ecb9607 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.

74f56632c3 d3d11: Use std::call_once()
g_once_init_enter() always takes global mutex for non-GCC build.
Use C++ once call implementation

1c3fac818d d3d11: Move GstD3D11Converter to gst-libs
The object is equivalent to GstVideoConverter but for D3D11.
Application can use this object directly for various conversions,
such as color space conversion, rescale, crop and flip/rotation.

fce7431381 d3d11: Install library headers
Our Direct3D11 abstraction layer has been improved and
it gained good shape from API point of view.
Also, On Windows, GstD3D11 has various advantages over GstGL
in terms of compatibility/stability/feature/performance.
Note that WGL implementation is known to be buggy for some
drivers/vendors/scenario (that's a reason why Google implemented ANGLE).
Moreover, GstGL is not fully optimized for Windows unfortunately.

It's the time to open this interface to application developers
for various optimized processing using our Direct3D11
infrastructure.

e5ba099fd8 d3d11device: Enhance format enumeration and debugging
* Enhance debug log to print human readable D3D11_FORMAT_SUPPORT flags
  value, instead of packed numeric flagset value.
* Only device supported format will be added to format table.
  Depending on device feature level (i.e., D3D9 feature devices),
  16bits formats will not be supported. Although there might be formats
  we deinfed but not supported, it will not be a major issue in practice
  since our D3D11 implementation does not support legacy devices already
  (known limitation) and also old d3dvideosink will be promoted in that case.

dd906f9610 d3d11: Store device format in struct
Holding pointer to struct was unsafe approach because
the pointer to d3d11 format will be invalidated once d3d11 device
object is released

e96687d88d d3d11: Update build-time dependency
Remove all the d3d11 and dxgi header version dependent ifdef
and bump the minimum requirement to d3d11_4.h and dxgi1_6.h.
We are already failing support old Visual Studio (Windows SDK actually)
such as Visual Studio 2015. Note that our MinGW toolchain satisfies
the requirement.

From runtime point of view, this change should be fine since
we are checking OS version with IUnknown::QueryInterface()
everywhere in order to check API availability
