Revert "Slab-allocate VkDescriptorSets"

This reverts commit 96c4019214e0b2d7c0843eacf96398a6a1198d1f.

Reason for revert: Breaks the roll, WebGPU CTS hits the
ASSERT(totalDescriptorCount > 0)

Original change's description:
> Slab-allocate VkDescriptorSets
> 
> This introduces a slab allocator for VkDescriptorSets which creates
> a VkDescriptorPool pre-allocated with multiple VkDescriptorSets per
> BindGroupLayout. In the future, we can deduplicate pools that have
> the same, or roughly the same, descriptor counts.
> 
> This CL also removes the old DescriptorSetService and moves most of
> the functionality onto the DescriptorSetAllocator itself to keep
> the tracking logic in one place.
