This significantly simplifies the calling code from Dawn.
It does require moving the SingleEntryPoint transform above the
renamer, since we need to call SEP with the original name. That is
probably also an optimization, since we do the subsequent transforms
with a culled AST.

Move builtin_to_string() and builtin_type() to
the CanonicalizeEntryPointIO transform. Use the former to
rename entry point IO variables to the gl_ names, and the latter
to cast values to the correct type.

More line() and less std::endl.
More automated indents and less manual spacing.
Put a single newline after every struct and function declaration.
Note that this does touch every test result, but only affects whitespace.

This removes a lot of awkward logic from the MSL writer, and means
that we now handle all module-scope variables with the same transform.

MSL has a limit on the number of threadgroup memory arguments, so use
a struct to support an arbitrary number of workgroup variables.
This commit introduces a `State` object to this transform, which is
used to track which structs have been cloned eagerly, in order to
avoid duplicating them.

The refactored CanonicalizeEntryPointIO transform makes it much easier
to handle SPIR-V style IO as well, and doing this removes a lot of
duplicated code. Remove all of the SPIR-V transform code for shader IO
and vertex point size.

This is a major reworking of this transform. The old transform code
was getting unwieldy, with part of the complication coming from the
handling of multiple return statements. By generating a wrapper
function instead, we can avoid a lot of this complexity.
The original entry point function is stripped of all shader IO
attributes (as well as `stage` and `workgroup_size`), but the body is
left unmodified. A new entry point wrapper function is introduced
which calls the original function, packing/unpacking the shader inputs
as necessary, and propagates the result to the corresponding shader
outputs.
The new code has been refactored to use a state object with the
different parts of the transform split into separate functions, which
makes it much more manageable.

This reverts commit e5dbe24e94.
Reason for revert: Makes the Tint-Dawn roll fails because of
MSL compilation errors on as_type<uint>(-2147483648):
as_type cast from 'long' to 'uint' (aka 'unsigned int') is not allowed
as_type<uint>(-2147483647) compiles fine, so this is most
likely because the MSL compiler types the literal as a long
(since without the - it is larger than the max int32).
