Removing parsing support for the 'in' and 'out' storage classes is
enough to prevent anyone from using the old syntax. The Input and
Output storage classes will remain in the AST for now, as the SPIR-V
reader still has codepaths that use them, and the SPIR-V writer
currently still relies on them.

After implementing validation and fairly exhaustive tests, discovered
that conversion of scalar vector to bool vector did not work in the
spir-v backend. For module scope variables, we use and rely on the
FoldConstants transform to ensure no conversion needs to take place.
This is necessary because we cannot easily introduce temporary values
and refer to them when casting at module scope. Note that for the same
reason, module-level conversions are always constant foldable, so this
works. For function-level conversions, implemented support to emit a
comparison against a zero value, and store the result in the bool
vector.

Previously the Clone() of the AST would clone all the functions, globals
and type declarations in a temporary vector, then assign this to the
ast::Module. This meant that adding new module-scope declarations inside
callbacks of ReplaceAll() would place them right at the top, before any
of the cloned declarations.
As top-level declarations are not statements, ensuring that a new object
comes before the current ReplaceAll() declaration is surprisingly
tricky.
With this change, we can now safely assume that calling
ProgramBuilder::Var(), ProgramBuilder::Func(), ProgramBuilder::Alias()
or ProgramBuilder::Structure() inside a ReplaceAll() will add that
module-scoped declaration before the currently processed top-level
declaration.

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.

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.

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.
