Add new property to support application allocated GstCudaMemory.
CUDA memory alloc/free is a global device synchronization point
as if launching CUDA kernel on default CUDA stream. To avoid the global
synchronization, we added stream-ordered allocation support
which allocates CUDA memory asynchronously.
However, NVENC does not allow registering the stream-ordered
allocated memory. Thus encoder was allocating normal CUDA
memory in case that input CUDA memory is stream-ordered type.
In this commit, newly introduced property will allow application
to provide encoder with GstCudaBufferPool. Application can
preallocate sufficient amount of CUDA memory in advance
to avoid global device synchronization while pipeline is running.
For now, this pool is used only if input CUDA memory is allocated
via stream-ordered-allocation

As per the C++ standard, any usage of a std::set::iterator after it has
been erased from the collection results in undefined behaviour. This has
resulted in application crashes due to CUDA illegal address errors.
This commit fixes the issue by copying and incrementing the iterator
within any for-loops that also invoke std::set::erase.

Adding RGBA, RGBx, BGRA, BGRx, VUYA and RGB10A2_LE format support for performance.
However, these formats are not still recommended if upstream can support
native YUV formats (e.g., NV12, P010) since NVENC does not expose
conversion related optiones. Note that VUYA format is 4:4:4 YUV format
already but NVENC runtime will convert it to 4:2:0 format internally

Call input resource map functions (i.e., nvEncRegisterResource,
nvEncUnregisterResource, nvEncMapInputResource, and
nvEncUnmapInputResource) only once and reuse the mapped resources,
instead of per input frame map/unmap
