nvcodec: nvsldec: Refactor graphics api resource handling
...
* Move GL context object to GstNVDecoder object, and remove
duplicated handling of each codec decoder element
* Don't create GL context too early. We can create it only if
we need to negotiate with downstream gl element.

nvcodec: nvdecoder: Move to refcount based GstNvDecoderFrame
...
This refcount based way would be helpful for sharing nvdec frame among
multiple codec pictures and later zero-copy use case.

nvcodec: Add H264 stateless codec implementation
...
Introduce GstH264Decoder based Nvidia H.264 decoder element.
Similar the element factory name of to v4l2 stateless codec,
this element can be configured with factory name "gstnvh264sldec".
Note that "sl" in the name stands for "stateless"
For now, existing nvh264dec covers more profile and formats
(e.g., interlaced stream) than this implementation.
However, this implementation allows us to control lower level
parameters such as decoded picture buffer management and therefore
we can get a chance to improve performance in terms of latency.
