Performs a module-scope (global) declaration dependency analysis, so
that out-of-order global declarations can be re-ordered into dependency
order for consumption by the resolver.
The WGSL working group are currently debating whether out-of-order
declarations should be included in WebGPU V1, so this implementation
currently errors if module-scope declarations are declared out-of-order,
and the resolver does not currently use this sorted global list.
The analysis does however provide significantly better error diagnostics
when cyclic dependencies are formed, and when globals are declared
out-of-order.
The DependencyGraph also correctly now detects symbol collisions between
functions and types (tint:1308).
With this change, validation is duplicated between the DependencyGraph
and the Resolver. The now-unreachable validation will be removed from
the Resolver with a followup change.

This patch add the size parameter check in buffer mapAsync in dawn
wire server to make sure that it is not WGPU_WHOLE_MAP_SIZE. Together
with validation in mapAsync in dawn native, we can ensure that the
size parameter deserialized in wire server is a valid actual size.
When using default size with dawn wire, the actual size is computed
by wire client, and WGPU_WHOLE_MAP_SIZE shall never be passed to server.

Use imageSize() on images, not textureSize().
In GLSL, the LOD parameter to textureSize() is mandatory for
sampled textures, so emit a default 0 if not supplied. (Also, don't pack
the level into the coords argument; that's an HLSLism.)
GLSL returns the array size of array textures in the final component
of textureSize(); remove it for WGSL.
Write the subtype of storage images correctly (uimage*, iimage*, etc).
This required a bit of cleanup to move "writeonly" ahead of subtype
emission.

ArrayLengthFromUniform is needed for correct bounds checks on
dynamic storage buffers on D3D12. The intrinsic GetDimensions does
not return the actual size of the buffer binding.
ArrayLengthFromUniform is updated to output the indices of the
uniform buffer that are statically used. This allows Dawn to minimize
the amount of data needed to upload into the uniform buffer.
These output indices are returned on the HLSL/MSL generator result.
ArrayLengthFromUniform is also updated to allow only some of the
arrayLength calls to be replaced with uniform buffer loads. For HLSL
output, the remaining arrayLength computations will continue to use
GetDimensions(). For MSL, it is invalid to not specify an index into
the uniform buffer for all storage buffers.
After Dawn is updated to use the array_length_from_uniform option in the
Metal backend, the buffer_size_ubo_index member for MSL output may be
removed.

Emit the "[loop]" attribute on "for" and "while" so that FXC does not
attempt to unroll them. This is to work around an FXC bug where it fails
to unroll loops with gradient operations.
FXC ostensibly unrolls such loops because gradient operations require
uniform control flow, and loops that have varying iterations may
possibly not be uniform. Tint will eventually validate that control flow
is indeed uniform, so forcing FXC to avoid unrolling in these cases
should be fine.
