Subject: Reduce the amount of descriptor pool allocations on Vulkan (#5673)

* Reduce the amount of descriptor pool allocations on Vulkan

* Formatting

* Slice can be simplified

* Make GetDescriptorPoolSizes static

* Adjust CanFit calculation so that TryAllocateDescriptorSets never fails

* Remove unused field
