1. Add some comments explaining what headers and libs are expected on
what systems
2. Only look in default incdirs if no incdir is specified
3. Require libnvbufsurface.so on Jetson when cuda-nvmm=enabled
4. Require libatomic on Jetson when cuda-nvmm=enabled

This commit enables the usage of inline queries, if and only if, the
provided
pNext structure, in gst_vulkan_opeation_enable_query(), chains a
VK_STRUCTURE_TYPE_VIDEO_PROFILE_INFO_KHR typed structure.
Also it guards "gstvkvideo-private.h" include

This relation type define relations between each components of two groups.
First component of first group relate to first component of second group,
Second component of second group relate to second component of second group,
and so on. It's a denser way to express relations in this context.

We get loads of warnings when parsing videos from users:
gsth264parser.c:1115:gst_h264_parser_parse_user_data_unregistered: No more remaining payload data to store
gsth264parse.c:646:gst_h264_parse_process_sei:<h264parse0> failed to parse one or more SEI message
Those are raised because of unregistered SEI without user data.
The spec does not explicitly state that unregistered SEI needs to have
data and I suppose the UUID by itself can carry valuable information.
FFmpeg also parses and exposes such SEI so there is no reason for us no
too as well.

It creates a new structure for passing the codec quality structure at _start(),
where it will be filled. The quality level can be set or changed according
encoder limits.
Later the quality level will be set at _update_session_parameters() and at each
frame encoding. That's why it has to be set at _start().

The algorithm for generating the current slot index is a simple round robin,
nonetheless it's not assured that the next slot index it's not still used by a
still living encode picture.
This new way holds an array with the still living encode pictures and the next
slot index looks for a released index in the array.
Its downside is deallocating a picture need to be removed from the array, so the
helper has to be passed to the uninit() function

In GStreamer that buffer information is decoupled, holding other structures to
describe the stream: GstCaps. So, to keep the GStreamer design this patch
removes these information from GstVulkanEncoderPicture and pass to
gst_vulkan_encoder_encode() a pointer to GstVideoInfo.

Instead of holding all headers in an external array and add them into the
bitstream buffer before the encoding operation, adding extra memory and extra
copy operations, the encoder picture should specify the offset where the Vulkan
will start to add the bitstream slices/frame, because the element has written
already the headers until that offset.

That's the number of references that gst_vulkan_encoder_encode() receives to
process, so it has to go as a parameter, because it's part of the reference
list, not of the picture.
This commit also modified unit tests accordingly.

The structure already stored the generic video capabilities and the specific
codec capabilities both for encoding an decoding. The generic decoder
capabilities weren't stored because it was only used internally in the decoder
helper object. Nonetheless, for the encoder, the elements will need the generic
encoder capabilities to configure the encoding. That's why it's required to
expose it as part of GstVulkanVideoCapabilities. And the generic decoder is
included for the sake of symmetry.
While updating the API vkvideoencodeh265 test got some code-style fixes.

First remove validations since they will fail if there isn't a write operation.
It's valid to pass data without write operations.
Finally, it should check for hasOverride in feedback info. Nonetheless, there's
a NVIDIA bug returning always FALSE for hasOverride, that's why we currently
force it to TRUE.
