24d096597b vulkan: implement caching and reuse of a couple of vulkan resources
Includes a new GstVulkanHandlePool base class for pooling different
resources togther.  The descriptor cache object is ported to
GstVulkanHandlePool with the exact same functionality.

A new GstVulkanFenceCache is also implemented for caching fences
which is used internally by GstVulkanDevice for creating or reusing
fences.

The existing GstVulkanTrashFenceList object now caches trash objects.

32b3387ae6 vulkan: implement proper descriptor set handling
The major functionality gain this provides is proper reference counting
for a descriptor set.  Overall this allows us to create descriptor sets
when they are needed (or reused from a cache) without violating any of
vulkan's object synchronisation requirements.

As there are a fixed number of sets available in a pool, the number of
descriptors in elements is currently hardcoded to 32.  This can be extended
in a future change to create pools on the fly if that limit is ever overrun.
