nvdec,nvenc: Port to dynamic library loading ... and put them into new nvcodec plugin. * nvcodec plugin Now each nvenc and nvdec element is moved to be a part of nvcodec plugin for better interoperability. Additionally, cuda runtime API header dependencies (i.e., cuda_runtime_api.h and cuda_gl_interop.h) are removed. Note that cuda runtime APIs have prefix "cuda". Since 1.16 release with Windows support, only "cuda.h" and "cudaGL.h" dependent symbols have been used except for some defined types. However, those types could be replaced with other types which were defined by "cuda.h". * dynamic library loading CUDA library will be opened with g_module_open() instead of build-time linking. On Windows, nvcuda.dll is installed to system path by CUDA Toolkit installer, and on *nix, user should ensure that libcuda.so.1 can be loadable (i.e., via LD_LIBRARY_PATH or default dlopen path) Therefore, NVIDIA_VIDEO_CODEC_SDK_PATH env build time dependency for Windows is removed.

nvcodec: Add CUDA specific memory and bufferpool Introducing CUDA buffer pool with generic CUDA memory support. Likewise GL memory, any elements which are able to access CUDA device memory directly can map this CUDA memory without upload/download overhead via the "GST_MAP_CUDA" map flag. Also usual GstMemory map/unmap is also possible with internal staging memory. For staging, CUDA Host allocated memory is used (see CuMemAllocHost API). The memory is allowing system access but has lower overhead during GPU upload/download than normal system memory.

Additionally, cuda runtime API header dependencies (i.e., cuda_runtime_api.h and cuda_gl_interop.h) are removed. Note that cuda runtime APIs have prefix "cuda". Since 1.16 release with Windows support, only "cuda.h" and "cudaGL.h" dependent symbols have been used except for some defined types. However, those types could be replaced with other types which were defined by "cuda.h". * dynamic library loading CUDA library will be opened with g_module_open() instead of build-time linking. On Windows, nvcuda.dll is installed to system path by CUDA Toolkit installer, and on *nix, user should ensure that libcuda.so.1 can be loadable (i.e., via LD_LIBRARY_PATH or default dlopen path) Therefore, NVIDIA_VIDEO_CODEC_SDK_PATH env build time dependency for Windows is removed.

nvcodec: Add CUDA specific memory and bufferpool Introducing CUDA buffer pool with generic CUDA memory support. Likewise GL memory, any elements which are able to access CUDA device memory directly can map this CUDA memory without upload/download overhead via the "GST_MAP_CUDA" map flag. Also usual GstMemory map/unmap is also possible with internal staging memory. For staging, CUDA Host allocated memory is used (see CuMemAllocHost API). The memory is allowing system access but has lower overhead during GPU upload/download than normal system memory.

nvcodec: Fix crash on 32-bit Windows We weren't using the correct calling convention when calling CUDA and CUVID APIs. `CUDAAPI` is `__stdcall` on Windows. This was working fine on x64 because `__stdcall` is ignored and there's no special calling convention. However, on x86, we need to use `__stdcall`.
