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.

Pull the HLSL transformation out to a standalone transform that can be
used by both HLSL and MSL.
The new E2E tests do not yet pass for MSL because they produce array
assignments, which will be addressed in the next patch.

Add a transform that pushes these into the entry point and then passes

Since WGSL does not allow non-function storage class at

Adds additional modes to the Renamer for renaming just HLSL or MSL
keywords. The sanitizers no longer rename reserved keywords
automatically, which isn't usually necessary anyway since Dawn renames
all symbols.
The tint executable automatically renames reserved keywords when
targeting HLSL and MSL. It now also has an option to rename
everything, which is useful for testing the renamer.

In anticipation of adding support for type inference, no longer use
ast::Variable::type() everywhere, as it will eventually return nullptr
for type-inferred variables. Instead, the Resolver now stores the final
resolved type into the semantic::Variable, and nearly all code now makes
use of that.
ast::Variable::type() has been renamed to ast::Variable::declared_type()
to help make its usage clear, and to distinguish it from
semantic::Variable::Type().
Fixed tests that failed after this change because variables were missing
VariableDeclStatements, so there was no path to the variables during
resolving, and thus no semantic info generated for them.

This change begins the work to move the reserved keyword remapping out of the writer and into the sanitizer transform.
If the transform::Renamer is in use, then these symbols should never have to be remapped - however for debugging purposes it is often nice to be able to emit code that isn't entirely mangled.
The logic in the msl writer will be removed as a followup change
