11ed0db30d resolver: Don't use ast to_str() methods 
These return weird names that love the use of '__' and have little relation to WGSL.

Improve the duplicate case error message.

Clean up control_block_validation_test.cc by making used of the ProgramBuilder helpers.

a9f8c7db81 Implement GLSL writer backend. 
This is a modified version of the HLSL writer.
Basic types, arrays, entry points, reserved keywords, uniforms,
builtin uniforms, structs, some builtin functions, zero initialization
are implemented. Textures, SSBOs and storage textures in particular are
unimplemented. All the unit tests "pass", but the output is not correct
in many cases.

triangle.wgsl outputs correct vertex and fragment shaders that pass
GLSL validation via glslang. compute_boids.wgsl outputs a valid but not
correct compute shader.

f66f651374 transform/BindingRemapper: Validate access mode 
Ensure that remapped access modes are valid enum values.

NB: This is hard to test, as UBSan flags an out-of-range enum value as
a hard error.

2ebcb93cb3 reader/spiv: Fix typo in entry-point IO sorting 
We were sorting the inputs twice.
Also make use the UniqueVector::operator std::vector() to simplify the code a little.

Doesn't appear to change any tests.
Just spotted while looking through code.

b7bcbf0d20 Resolver: Traverse expressions without recursion 
This CL changes the way that the resolver traverses expressions to avoid stack overflows for deeply nested expressions.

Instead of having the expression resolver methods call back into
Expression(), add a TraverseExpressions() method that collects all the
expression nodes with a simple DFS.

This currently only changes the way that Expressions are traversed. We
may need to do the same for statements.

3646400342 transform: Add ModuleScopeVarToEntryPointParam 
This is the HandleModuleScopeVars() part of the MSL sanitizer moved
verbatim to a standalone transform. The transform code is unchanged,
but some expected test outputs are different as this is now tested in
isolation instead of along with the rest of the sanitizer transforms.

This is step towards removing the sanitizers completely.
