Use a transform to convert these to the vector form for the MSL and
SPIR-V backends.

MSL only has the scalar form from version 2.0 onwards.

8648120bbe Make all ast and sem pointers const 
And remove a whole load of const_cast hackery.

Semantic nodes may contain internally mutable fields (although only ever modified during resolving), so these are always passed by `const` pointer.

While all AST nodes are internally immutable, we have decided that pointers to AST nodes should also be marked `const`, for consistency.

There's still a collection of const_cast calls in the Resolver. These will be fixed up in a later change.

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.

7cf3b28a87 GLSL writer: validate all entry points with glslang. 
Generate and validate all entry points individually.
This is required since GLSL has separate shader files, and
can only have a single "main" entry point.

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.
