writer/wgsl: Fix all tests that had unreachable AST nodes 

By making nodes reachable, the resolver has now caught a whole lot of additional problems, which have been fixed in this CL.

Some of these broken tests were attempting to use private and workgroup variables as function-scope declarations.
This is not legal, and these have been moved to module-scope variables.
