Ben Clayton 3103a1f666 BindingRemapper: Allow for binding point collisions
Add a new parameter to BindingRemapper::Remappings that allows resulting binding points to collide.

When enabled, the output of the transform contains two or more module-scoped variables with the same binding point, used by the same entry point, then these variables will be decorated with an internal decoration to disable validation for the collision.

This is to work around collisions generated for the HLSL backend where the variables actually exist in different register classes, which is permitted by D3D12.

The transform will only generate these decorations if it needs to.

Ben Clayton 451f2cc68a Add ast::DisableValidationDecoration
An [[internal]] decoration that specifically disables certain validation checks.
Begin with a single kFunctionHasNoBody mode.
Migrate the Resolver to using this instead of allowing any InternalDecoration to disable the checks for no-body.

Ben Clayton 5df7661659 Resolver: Move common logic into Variable()
Variable() is called for globals, locals and parameters. Much of the logic is the same.

Move all the common logic down into Variable(). This:
* Removes some yucky default parameters
* Adds type validation that was missing for globals (broken tests fixed)
* Gives me a single place to implement the Reference type wrapping

Ben Clayton fcda15ef67 Move storage_class validation from wgsl to resolver
We don't want the WGSL parser to have to maintain type lookups.
If the WGSL language is updated to allow module-scope variables to be declared in any order, then the single-pass approach is going to fail horribly.

Instead do the check in the Resovler.
With this change, the AST nodes actually contain the correctly declared storage class.

Fix up the SPIR-V reader to generate StorageClass::kNone for handle types.
Fix all tests.

Ben Clayton 02ebf0dcae ast: Migrate to using ast::Type
Remove all sem::Type references from the AST.
ConstructedTypes are now all AST types.

The parsers will still create semantic types, but these are now disjoint
and ignored.
The parsers will be updated with future changes to stop creating these
semantic types.

Resolver creates semantic types from the AST types. Most downstream
logic continues to use the semantic types, however transforms will now
need to rebuild AST type information instead of reassigning semantic
information, as semantic nodes are fully rebuilt by the Resolver.

Ben Clayton cf28b5aafe resolver: Call ValidateVariable() for globals
This was only called for function-scope variable declarations.
In calling this, there were inevitable tests failing, which have now been fixed.
Added a test for the single runtime-array-length validation rule that this function was checking.

Ben Clayton 6fcefe4c25 Resolver: Check that every AST node is reached once
AST nodes must not be shared. Diamonds in the AST will cause all sorts
of exciting, non trivial bugs.

All AST nodes must be reached by the Resolver. There are two common
reasons why they may not be:
(a) They were constructed and not attached to the AST. Several
    transforms scan the full list of constructed AST nodes to find nodes
    of a given type. Having detached nodes will likely cause bugs in
    these transforms. Detached nodes is also just a waste of memory.
(b) They are attached to the AST, but the resolver did not traverse
    them. Having the resolver skip over parts of the AST will fail to
    catch validation issues, and will leave semantic gaps, likely
    breaking downstream logic.

Ben Clayton 1773535e1c Resolver: Validate <storage> var types
https://gpuweb.github.io/gpuweb/wgsl/#variable-declaration
Variables in the storage storage class and variables with a storage
texture type must have an access attribute applied to the store type.

https://gpuweb.github.io/gpuweb/wgsl/#module-scope-variables
A variable in the storage storage class is a storage buffer variable. Its
store type must be a host-shareable structure type with block attribute,
satisfying the storage class constraints.

Fixup tests, including those that were producing warnings about `var <in>`

The WGSL writer seems to want to put a newline after every decoration block, leading to some ugly output. I'll fix this as a separate change.
