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.

nvdec: Don't hardcode DPB size Too many decode surface would waste GPU memory. Also it seems to be introducing additional latency depending on stream. Since nvcodec sdk version 9.0, CUVID parser API has been providing the minimum required number of surface. By using it, we can save GPU memory and reduce possible latency.

nvdec: Register elements per device/codec with capability check By this commit, each codec has its own element factory so the nvdec element factory is removed. Also, if there are more than one device, additional nvdec element factory will be created per device like nvh264device{device-id}dec, so that the element factory can expose the exact capability of the device for the codec.

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`.
