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.

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.

Add a config parameter for the CanonicalizeEntryPoint transform that
selects between emitting builtins as parameters (for MSL) or struct
members (for HLSL).
This fixes all of the shader IO issues in Tint's E2E tests for MSL.

* Add new template utilty functions, including the ability to split out multiple files.
* Add basic printing of the semantic overloads.
* Add a pointer from the overload to the function
* Change TemplateArguments from a list of FQN to a list of interface{} (any). This is required as once the overload is permutated, some arguments will need to hold integers.
This will be used by the test generator.

Nothing was limiting the texel format to i32, u32, f32, and so the resolver was accepting any type here, and things would break in the backends.
Also limit texture access controls to read or write. read_write is not supported for textures currently.

Formerly, tmpnam_s was used to ensure a unique file name, but then we'd
append an extension to it, invalidating its uniqueness. Instead, we now
do our own uniqueness check by attempting to create a unique empty file
for write with new names until it succeeds.

Using WaitForMultipleObjects on the handles to stdout and stderr streams
is apparently not the right way to do this. Instead, we create 2
threads, one that reads stdout, and one that reads stderr, and we wait
on those threads, along with the process handle.

Previous logic relied on the fact that for most operations, for a given
lhs type, there was exactly one rhs type allowed, except for
multiplication. This is no longer true in the spec, so making this test
work is more complex now. Instead, we simplify the test by having it
take the cartesian product of all possible (type * type * op), and
skipping any triplet not found in the all_valid_cases table.

Add a transform that pushes these into the entry point and then passes
them by pointer to any functions that need them.
Since WGSL does not allow non-function storage class at
function-scope, add a DisableValidation attribute to bypass this
