This reverts commit fd5829e5ea.

Reason for revert: Temporarily reverting as this is preventing a tint->dawn roll, which is needed to fix the dawn->chrome roll.

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.

Ben Clayton 03d10721e7 Stop tint.h from including program_builder.h
ProgramBuilder is about as internal as you can get - this really should not be public.

MSVC seems to try an instantiate some of the template methods in ProgramBuilder when it is included externally (for PCH or DLL exports perhaps?), and failing with bizzare error messages that contain no point-of-instantiation.

As this header was never intended to be public in the first place, detect and error if the tint.h include guard is found while processing program_builder.h, and fix up the couple of bad transitive includes.

Ben Clayton 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.

Ben Clayton 620d77e480 PB: Make Var() and Global() params optional

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.

James Price 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.

Antonio Maiorano dc4e6c1844 Remove sem::AccessControl
In preparation for implementing
https://github.com/gpuweb/gpuweb/issues/1604, this change removes the
sem::AccessControl node. Instead, the ast::AccessControl::Access enum is
now on the sem::StorageTexture class, as well as on sem::Variable. For
sem::Variable, the field is set when the variable's type is either a
storage buffer or a storage texture.

Ben Clayton f6c84e4d45 Use StorageClass::kNone for ast local var decls
To declare a local variable, we write `var name : type`, not `var<function> name : type`.
This change fixes all the places where we were feeding StorageClass::kFunction into variable declarations.

Note that the resolved, semantic variable correctly infers the `kFunction` StorageClass.
