This uses template and macro magic to reflect the fields of a class.
Dawn:
* Reflect the fields of the types that are used by Dawn's stream::Stream<T> specializations, and use tint::ForeachField() to call StreamIn().
Fuzzers:
* Replace tint::fuzzers::DataBuilder::BuildImpl<T> specializations with the new reflection system.
* 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.
All this reduces fragility of the struct declarations slipping out of sync with the uses.

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 a call to atan2 with args of type AFloat and AInt is made, Resolver
would correctly select the atan2(AFloat, AFloat) overload, but if the
input args were of type (AFloat, AInt), it would attempt to constant
evaluate without first converting the AInt arg to AFloat. The same would
occur for a binary operation, say AFloat + AInt. Before constant
evaluating, the Resolver now converts AInt to AFloat if necessary.

This Cl updates the parser implementation of the `global_decl` rule.
The `type_alias` rule is renamed to `type_alias_decl` and the `struct`
parsing is moved out of the synchronization to `;` code as a `struct`
no longer has a trailling `;`.

Fixes "dxc failed : unable to parse shader model.".
On windows the called program is responsible for splitting arguments
from one joined string. Command line arguments on 'nix systems need to
be passed as separate strings. This CL makes it so that we pass in the
arg separately, and support ignoring empty string args to make writing
this code easier.

This patch add DXC compile flag "-enable-16bit-types" and change profile
to SM6.2 when validating generated HLSL using DXC if f16 extension is
enabled in the WGSL program.
The patch add Tint end-to-end test cases for expressions using f16 type,
including constructor, binary operator, splat, zero-init, and others.
Testcases that use f16 types in uniform or storage buffer are SKIPped,
because such usage is not implemented yet.

The elements of the VectorRef is now immutable, but can be
moved, if the caller relinquishes ownership by explicitly using
std::move() at the callsite.
Also add utils::Empty as a way of signalling that a vector should be
constructed with no elements. This is helpful in templated code where
{} cannot be used due to overload ambiguity.

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.
