vkd3d: Rename push_descriptor_set to root_descriptor_set.

Soon it won't be used necessarily for push descriptors anymore, but
it will still contain root descriptors.

vkd3d: Put all root descriptors in a single Vulkan descriptor set when using Vulkan heaps.

Since 4a94bfc2f6c1ebfe4cac6c26ccf567339c71078f we segregate
different D3D12 descriptor types in different Vulkan descriptor sets.
This change was introduced to reduce descriptor wasting when
allocating a new descriptor pool; that can be very useful when
using virtual heaps, which have to often cycle through many
descriptors, but it is expected to have limited impact for Vulkan
heaps, given that in that case most descriptors are allocated through
the descriptor heap rather than through the command allocator.

Instead, it has a rather detrimental effect with Vulkan heaps,
because it tends to use many more Vulkan descriptor sets than
necessary, often with just a handful of descriptors each. This
causes a regression on some Vulkan implementations that support
too few descriptor sets.

With this change we revert to a situation similar to before,
stuffing all the descriptors that do not live in a root
descriptor table in as few descriptor sets as possible (at most
one or two, depending on whether push descriptors are used).
