All of these root constants are set when a bind group holding

Currently, the bind group layout tightly packs the shader registers for
each of the sampler and non-sampler descriptors sets. This reduces the
max shader register used and helps targeting shader model 5.0, which has
a relatively low max slot count per resource. It is safe in D3D, since a
shader register collision can be valid if the descriptor types differ.
To support Mesa's SPIR-V to DXIL compiler, we need to avoid possible
collisions between resources' shader registers because it uses SPIR-V as
an intermediate representation (which does not namespace bindings by
type). This change re-works BindGroupLayoutD3D12 to not assume the
resulting shader registers will be tightly packed and group per
descriptor type.

Allows bindgroups that use the same samplers to share
a descriptor heap allocation. This is particularly important
for sampler heaps which incur expensive pipeline flushes
due to the smaller size requiring more frequent switches.
The device dolls out entries to a sampler heap allocation cache.
When the BindGroup is created, it does a lookup and refs the
allocation. This ensures the cache does not grow unbounded
or needlessly store unused entires.
This change is a follow-up of de-coupling heaps.

In a typical graphics application it is a common usage to update some uniforms once per draw,
and such uniforms include the word positions, orientations, and so on. In the current state of
WebGPU, this means that for each draw call we have to create a new bind group to set the right
uniform values. Bind group creation is expected to be more expensive than
recording draws because a memory allocation is required.
The functionality of dynamic buffer offset is to reduce the number of bind groups that need to
be created.
The patch implements dynamic buffer offset on D3D backend using root descriptor.
