avutil/hwcontext_cuda: combine transfer functions
...
Gets rid of some mostly duplicated code and adds the ability to do
hardware to hardware transfers.

lavu/hwcontext_cuda: refactor context initialisation
...
There's enough going on here now that it should not be duplicated
between cuda_device_create and cuda_device_derive.

lavu: add Vulkan hwcontext code
...
This commit adds the necessary code to initialize and use a Vulkan device
within the hwcontext libavutil framework.
Currently direct mapping to VAAPI and DRM frames is functional, and
transfers to CUDA and native frames are supported.
Lets hope the future Vulkan video decode extension fits well within this
framework.

avutil/hcontext_cuda: Remove unnecessary stream synchronisation
...
Similarly to the previous changes, we don't need to synchronise
after a memcpy to device memory. On the other hand, we need to
keep synchronising after a copy to host memory, otherwise there's
no guarantee that subsequent host reads will return valid data.

avutil/hwcontext_cuda: Define and use common CHECK_CU()
...
We have a pattern of wrapping CUDA calls to print errors and
normalise return values that is used in a couple of places. To
avoid duplication and increase consistency, let's put the wrapper
implementation in a shared place and use it everywhere.
Affects:
* avcodec/cuviddec
* avcodec/nvdec
* avcodec/nvenc
* avfilter/vf_scale_cuda
* avfilter/vf_scale_npp
* avfilter/vf_thumbnail_cuda
* avfilter/vf_transpose_npp
* avfilter/vf_yadif_cuda
