This patch adds the basic validation of read-only storage texture,
write-only storage texture and read-write storage texture as new
binding types with no bind group layout provided in the creation of
pipeline state objects.
- Read-only storage textures can be used in vertex, fragment and
compute shaders.
- Write-only storage textures can only be used in compute shaders
due to the limitation on Metal.
- Read-write storage textures are not allowed now and they are
reserved to be supported as an extension in the future.

This change implements D3D12 backend for readonly storage buffer.
It uses SRV in root signature at API side and ByteAddressBuffer at
shader side (has already been done in spirv-cross) for readonly
storage buffer.

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.

These additions to dawn.json don't require changes to users of the C++
API so they are done now to prepare for webgpu.h. Validation is added
that forbids using the new enum values and non-default values for
members until they are implemented.

WebGPU remove dynamic-uniform-buffer and dynamic-storage-buffer but add a new attribute in
BindgroupLayoutBinding to record whether a buffer resource is dynamic.
Dawn need to align with this change.

When both the vert and frag shaders have a UBO binding, the D3D12
backend was using register offset 0 for both, causing a collision,
and the wrong constant value used in one of the shaders.
The fix is to use the binding offsets computed by the BindGroupLayout,
since they know about all of the bindings, not just the ones computed
for each shader. This made it necessary to defer shader compilation
until pipeline layout creation time (as is done in the Metal backend
for similar reasons).
Finally, those bindings offsets computed by the BGL include an offset
for the CBV, UAV and SRV subgroups, so we must add the same register
offset when assigning the BaseShaderRegister to the descriptor ranges
in the PipelineLayout constructor so that they match.

The dawn.h and dawncpp.h structure definitions references dawnFoo or
dawn::Foo respectively when it should reference dawn_native::FooBase* in
dawn_native. Autogenerate files to declare the dawn_native version of
the structs and change the ProcTable generation to use it instead.
This is important to make libdawn_native a shared library because
currently it was depending on dawncpp's definition of .Get().
