dbf4915abd cuda/context: add gpu stack size property 
Allows reducing the initial stack size of GPU threads.  Cuda should
automatically increase this value if a kernel requires a larger stack.

Can save roughly 40MB of GPU memory for a single nvh264enc instance.

cdaa798ac7 cuda: Add methods to enable stream ordered allocation 
Adding prefer-stream-ordered-alloc property to GstCudaContext.
If stream ordered allocation buffer pool option is not configured
and this property is enabled, buffer pool will enable the stream
ordered allocation. Otherwise it will follow default behavior.

If GST_CUDA_ENABLE_STREAM_ORDERED_ALLOC env is set,
default behavior is enabling the stream ordered allocation.
Otherwise sync alloc/free method will be used.

992406cf4f cuda, nvcodec: Make GstD3D11 dependency mandatory 
GstD3D11 build-time dependencies should be always available on Windows already
and runtime dependencies as well, since required external
(non-GStreamer) depends are all system DLLs
