The level parameter needs to be zero for a number of texture overloads.
Bodging the template to emit 0 instead of 1 for any `level : i32` parameter is the easiest fix here.

Instead of just generating pointers to functions, generate pointers to all permuted storage types and accesses.

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.

This is required to generate valid MSL code, and will soon be
validated by Tint too.

Add test/intrinsics/intrinsics.wgsl.tmpl that generates a vast set of intrinsic overload permutations into test/intrinsics/gen/...
Add expected output for all of these, including 'SKIP' headers for those that currently fail.
