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.

Instead of dragging the last destination pipeline stage as current barrier
source pipeline stage (which isn't a valid semantic) this patch adds a parameter
to gst_vulkan_operation_add_frame_barrier() to set the source pipeline stage to
define the barrier.
The previous logic brought problems particularly with queue transfers, when the
new queue doesn't support the stage set during a previous operation in a
different queue.
Now the operation API is closer to Vulkan semantics.
