Ben Clayton f24b37e122 writer/msl: Rework string printing 
Add `out` parameters to expression and type generators.

Use the new helper classes in TextGenerator.
Cleans up bad formatting.

Prepares the writer generating 'pre' statements, required for atomics.

If-else statements are generated slightly differently. This is done so that 'pre' statements for the else conditions are scoped correctly. This is identical to the HLSL writer.

Ben Clayton 5d2f34ecf2 writer/hlsl: Simplify emission logic, clean up output 
And fix issues where global variables would not be emitted unless they were transitively referenced by an entry point.

This change requires crbug.com/tint/697 to be fixed before landing.

Ben Clayton b07a7cead6 [tools]: Generate intrinisic test cases 
Add test/intrinsics/intrinsics.wgsl.tmpl that generates a vast set of intrinsic overload permutations into test/intrinsics/gen/...

Add expected output for all of these, including 'SKIP' headers for those that currently fail.
