Modify the AddSpirvBlockAttribute transform to fix top-level structure
access of uniform, storage and push-constant buffers for use in the
GLSL backend. The small change to the transform makes the transform
wrap host-sharable buffers, if they're also used as a
non-host-sharable structure. Also rename the transform to
AddBlockAttrbibute in order to reflect its wider applicability.

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.

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 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.

If a module-scope private variable is only referenced within a single
function, promote it to a function scope declaration instead of
passing it as a parameter. This reduces the number of a function
parameters that are needed in some cases.

And remove the WrapArraysInStructs transform.
Wrapping arrays in structures becomes troublesome for `const` arrays, as
currently WGSL does not allow `const` structures.
MSL 2.0+ has a builtin array<> helper, but we're targetting MSL 1.2, so
we have to emit our own. Fortunately, it can be done with a few lines of
templated code.
This produces significantly cleaner output.

Adapt the builtin parsing and resolving to also support operators.
Will be used to generate intrinsic table entries for operators.
This will simplify maintenance of the operators, and will greatly
simplify the [AbstractInt -> i32|u32] [AbstractFloat -> f32|f16] logic.

Merge SintLiteralExpression and UintLiteralExpression with
IntLiteralExpression. IntLiteralExpression has a new Suffix field which
indicates whether the literal is either a:
• 'i' suffixed integer literal
• 'u' suffixed integer literal
• no-suffix integer literal
Have the SPIR-V reader produce no-suffixed literals for i32 types, to
keep this change small. In future changes the SPIR-V reader will
produce 'i' suffixed types for these.
Have all consumers of IntLiteralExpression treat unsuffixed integers the
same as 'i'-suffixed literals. Unsuffixed will be treated as abstract in
future changes.
Removed SemHelper::TypeOf(const ast::LiteralExpression* lit).

Instead of using an `if` node that has a list of `else` statements,
make each `if` statement have a single optional `else` statement,
which may itself be an `if` statement (or just a block statement).
This better matches the WGSL grammar (now that we have removed
`elseif`), and simplifies various pieces of code that handle these
statements.

getting all used enable directives' extension names and location.
4. For different writer, the extension nodes are handled in different
ways. MSL and HLSL writers will just ignore the extension nodes, while
SPIRV and GLSL writers will emit corresponding code.
