cudaupload,cudadownload: Don't simplify caps in transform_caps
...
The simplified caps might not be a subset of filter caps
and basetransform will complain about it.

cudadownload: Passthrough in case of CUDA -> SYSTEM
...
GstCudaMemory supports CPU access via CUDA pinned host memory already
and it would show faster memory transfer performance between
GPU and CPU than copying from/to normal system memory.
If downstream supports video meta, we can passthrough CUDA memory.

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
