Since GLSL ES does not support the offset= attribute, struct members
with explicit @align or @size attributes require adding explicit
padding members. This in turn requires rewriting any constructor
calls to initialize the new padding to zero, handled in the same
transform.
Note that this is currently overly-verbose, and will add padding where
GLSL doesn't technically need it (e.g., padding a vec3 out to 16 bytes).

If the let initializer was an abstract numeric that was implicitly materialized to a concrete type, then we could inlining the initializer into the use without the implicit materialization cast.
This could lead to validation errors, and subtly different results in the program.
In this situation, add an explicit cast to keep the types the same before and after inlining.

* static_assert that the type is either POD or reflected. Add a specialization for std::optional which was missing.
Move tint::transform::BindingPoints into MultiplanarExternalTexture, as this is only used by MultiplanarExternalTexture.

Expand the Option argument paradigm to:
* Remove the requirement to always pass a 'type' parameter. Type inferencing is the easier, and increasingly common way to declare a variable, so this prevents a whole lot of `nullptr` smell which negatively impacts readability.
* Accept attributes directly as arguments, removing the `utils::Vector{ ... }` smell.
Rename `ProgramBuilder::VarOptionals` to `VarOptions`, and add equivalent `LetOptions`, `ConstOptions` and `OverrideOptions`.
Clean up all the calls to `Var()`, `Let()`, `Const()` and `Override()`:
* Use the `Group()` and `Binding()` helpers where possible
* Removing `nullptr` type arguments
* Replace attribute vectors with the list of attributes.
* Remove already-defaulted `ast::StorageClass::kNone` arguments.
* Remove already-defaulted `ast::Access::kUndefined` arguments.
Finally, remove the `GroupAndBinding()` helper, which only existed because you needed to pass attributes as a vector.

If the return value of a builtin is a constant value, it may be an
abstract number, and our backends currently do not deal with abstract
numbers. As these builtins have no side-effects, and the return value is

This is needed for the follow-up CL that fixes calls to builtins with

This extension adds support for the push_constant storage class such
that it can be tested with WGSL test files. The real goal is to allow
future transforms that will add push constants that the SPIRV writer
will output.
The extension:
- Adds the `chromium_experimental_push_constant` enable.
- Allows the push_constant storage class for global variables.
- Adds validation that the types are host-shareable for push_constant
variables, and that they don't contain f16 (must be 32bit types
only).
- Validates that at most one push_constant variable is statically used
per entry-point.
- Skips validation that the extension has been enabled if
kIgnoreStorageClass is used.
Tests are added:
- For parsing of var<push_constant>
- Caught a missing conversion.
- For each of the validation rules.
- For the wrapping of push constants in structs if needed by
AddSpirvBlockAttribute.
- For the layout and type rules of the storage class.
- For a shader with multiple entry-points using various push constants.
- Caught a missing reset of the previous push constant variable in
the validation check that at most one is used.
- Caught the missing wrapping in structs that had to be added to
AddSpirvBlockAttribute.
- Caught incorrect logic when adding diagnostics about the call
graph leading to the reference to push constants.
