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.

This implements the uniformity analysis as currently described in the
WGSL specification. Uniformity issues are presented as warnings, and
will be switched to errors in a future release.
A follow-up patch will improve the error messages, which currently
just show the point at which a uniformity was detected.
In a future release, once we have obtained initial feedback from
users, uniformity issues will become errors.

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.
