989a8e4d62 validation: Validate interpolation attributes
They are only valid on entry point parameters and return types, and
struct members. They must only be used on floating point scalar and
vector types. If the interpolation type is flat, the sampling type

Entry point function parameter can only have builtin and location

Fix parameter creation in the CanonicalizeEntryPointIO transform for a

14c0b8acbf Validate that in/out storage classes are not used
Use a DisableValidationDecoration to allow these storage classes only
for variables generated by the SPIR-V sanitizer. This is also used in
the Inspector tests, since the Inspector is currently run *after* the
SPIR-V sanitizer. These tests will be removed when this is no longer
the case.

Also validate that builtin/location decorations are not used on
variables (unless they have input/output storage class).

Fix or delete all of the other tests that were wrongly using these
storage classes and attributes.

8758f10a20 ast: Replace NamedType with TypeDecl
TypeDecls (alias, structure) are not a types - they declare types.
ast::TypeName is what's used for a ast::Type.

Previously we were trying to automatically convert these to TypeNames in the builder, but having these inherit from ast::Type was extremely error prone.

reader/spirv was actually constructing ast::Structs and using them as types, which is invalid.

93e8f527ee wgsl: Deprecate [[access]] decorations
Handle access control on var declarations instead of via [[access]]
decorations. This change does the minimal work to migrate the WGSL
parser over to the new syntax. Additional changes will be needed
to correctly generate defaulted access qualifiers, as well as
validating access usage.

The [[access]] decorations are still supported by the WGSL parser,
with new deprecated warnings, but not for aliases. Example:
   var x : [[access(x)]] alias_to_struct;

Making this work is far more effort than I want to dedicate to backwards
compatibility, and I do not beleive any real-world usage will be doing
this.

Still TODO:
* Adding access control as the optional, third parameter to ptr<>.
* Calculating default accesses for the various storage types.
* Validating usage of variables against the different accesses.

620d77e480 PB: Make Var() and Global() params optional
and allow them in any order.

We're about to add Yet Another optional parameter - access control.
For style, we probably want this field before the decorations, however
that means adding more default values for all the cases where we don't
need to specify the access control.

Instead use some template magic to allow extra parameters to be
specified in any order, and entirely optional, with sensible defaults.
This keeps things readable and without huge code refactorings.

70f80bb13d ast: Support non-literal workgroup_size parameters
Change the type of the values in an ast::WorkgroupDecoration to be
ast::Expression nodes, so that they can represent both
ast::ScalarExpression (literal) and ast::IdentifierExpression
(module-scope constant).

The Resolver processes these nodes to produce a uint32_t for the
default value on each dimension, and captures a reference to the
module-scope constant if it is overridable (which will soon be used by
the inspector and backends).

The WGSL parser now uses `primary_expression` to parse arguments to
workgroup_size.

Also added some WorkgroupSize() helpers to ProgramBuilder.

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.

8a8d26bbd9 ast: Add type nodes
Copy all of the type classes from src/type into ast.

Required the merging of:
* type::Struct into the existing ast::Struct - ast::Struct now has a name.
* type::AccessControl into the existing ast::AccessControl enumerator - The old ast::AccessControl enumerator is now ast::AccessControl::Access

cf4057be01 Rename type::Array to type::ArrayType
This is to avoid name conflicts once we move all classes from namespace
`type` to `sem`.

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.

648b05e4e2 Fix AttemptTintPadSymbolCollision test
This test landed simultaneously with a change that checks that storage buffers have an access qualifier, leading to broken tests.

Also fix lint issues that have crept in.

bbbb0edec2 Move global var validation from Validator to Resolver
* Moved global variable resolving logic to new function Resolver::GlobalVariable, and moved validation logic there.
* Moved global variable-related tests to resolver tests.
* Fixed many tests that started failing after this change, mainly because many globals were declared with no storage class. I set most of these to "Input".

03c01b5266 Move function validation from Validator to Resolver
* Fixed many tests that now failed validation. Most of the time,
functions declared that they returned a type, but with no return
statement.
* ProgramBuilder::WrapInFunction now returns the function is creates,
and std::moves its StatementList.
* ProgramBuilder: Added Return function to create ast::ReturnStatements
more easily.

9970ec63ca Move struct validation from Validator to Resolver
* Moved Validator::ValidateConstructedType, which only validated
structs, to Resolver as ValidateStructure.
* Moved relevant tests to new files, and also updated all failing tests
to validate Source location.
* Fixed other tests that broke now that we're validating structs.
