cuda: Add YUY2 and UYVY formats for GL interop
...
Those formats are not supported conversion formats by CUDA convert/scale elements
but would be useful for GL <-> CUDA interop use case.

cudaupload,cudadownload: Add support for dGPU NVMM
...
Implement NVMM <-> CUDA, GL, SYSTEM memory conversion. Jetson is
not supported yet. Note that NVMM <-> GL interop on Jetson platform
is supported by GstGL
Some example pipelines are:
- Convert NVMM to GstGL memory
nvv4l2decoder ! "video/x-raw(memory:NVMM)" ! cudadownload ! "video/x-raw(memory:GLMemory)" ! glimagesink
- Upload system memory to NVMM and encode
video/x-raw,format=NV12 ! cudaupload ! "video/x-raw(memory:NVMM)" ! nvv4l2h264enc
- Convert NVMM to GstCUDA memory and encode
nvvideoconvert ! "video/x-raw(memory:NVMM)" ! cudaupload ! "video/x-raw(memory:CUDAMemory)" ! nvh264enc

nvcodec: Refactor cudaupload/download and add support for GL memory
...
* Implement new baseclass GstCudaMemoryCopy to remove duplicated
cudaupload/download code
* Add support for CUDA <-> GL memory conversion via cudaupload/download

nvcodec: Refactor basetransform subclasses
...
* cudaupload/download
- Specify only formats actually we can deal with
nvcodec elements, not all video formats
- Supports CUDA output for download and input for upload in order
to make passthrough possible, like other upload/download elements.
* cudabasetransform
- Reset conversion element if upstream CUDA memory
holds different CUDA context and the element can accept it.
This is the same behavior as corresponding d3d11 filter elements.
