6ba1ee8d0f d3d11videoprocessor: Disable auto processing mode explicitly
Don't allow auto processing (e.g., denoising), as it might result
in unexpected output.

0f7af4b143 d3d11: Move core methods to gst-libs
Move d3d11 device, memory, buffer pool and minimal method
to gst-libs so that other plugins can access d3d11 resource.
Since Direct3D is primary graphics API on Windows, we need
this infrastructure for various plugins can share GPU resource
without downloading GPU memory.
Note that this implementation is public only for -bad scope
for now.

59a1897c39 d3d11: Privatize d3d11memory implementation
Hide most of symbols of GstD3D11Memory object.
GstD3D11Memory is one of primary resource for imcoming d3d11 library
and it's expected to be a extensible feature.
Hiding implementation detail would be helpful for later use case.

Summary of this commit:
* Now all native Direct3D11 resources are private of GstD3D11Memory.
  To access native resources, getter methods need to be used
  or generic map (e.g., gst_memory_map) API should be called
  apart from some exceptional case such as d3d11decoder case.
* Various helper methods are added for GstBuffer related operations
  and in order to remove duplicated code.

b62867ecc8 d3d11videoprocessor: Fix wrong input/output supportability check
The flag argument of ID3D11VideoProcessorEnumerator::CheckVideoProcessorFormat
method is output value, not input.

969ab3e664 d3d11convert: Add support for conversion using ID3D11VideoProcessor
Output texture of d3d11 decoder cannot have the bind flag
D3D11_BIND_SHADER_RESOURCE (meaning that it cannot be used for shader
input resource). So d3d11convert (and it's subclasses) was copying
texture into another internal texture to use d3d11 shader.
It's obviously overhead and we can avoid texture copy for
colorspace conversion or resizing via ID3D11VideoProcessor
as it supports decoder output texture.
This commit would be a visible optimization for d3d11 decoder with
d3d11compositor use case because we can avoid texture copy per frame.

35ed7c7811 d3d11window: Reuse ID3D11VideoProcessorInputView if possible
GstMemory object could be disposed if GstBuffer is not allocated
by GstD3D11BufferPool such as via gst_buffer_copy() and/or
gst_buffer_make_writable(). So attaching qdata on GstMemory
object would cause unnecessary view alloc/free.
By using view pool which is implemented in GstD3D11Allocator,
we can avoid redundant view alloc/free.

122a9b93eb d3d11: Add video processor object
ID3D11VideoProcessor interface provides various image conversion
methods. Note that it's analogous to VAAPI VPP.
