* Formerly, we reported the same error message if we detected no default
clause or more than one. I made it so that we output a different error
message for each. This makes it more clear, and in the case of more than
one, the error source location points at the second default clause,
rather than at the switch statement.
* Add functions to ProgramBuilder to more easily define switch and case
statements.
* Fix broken tests as a result of this change.

Call validation was already implemented in Resolver. This change
completes it by deleting the relevant code in Validator, and moving and
updating the builtins validation test to use the Resolver.
Also added the "v-0004" error code for when detecting recursion, as was
done for the similar error in the Validator.

This isn't in the WGSL spec, nor is it generated by readers.
This was only used inside the SPIR-V writer, but this remaining usage was removed in the parent change.

Requiring a temporary stack-allocated ast::Literal is an unpleasant requirement to generate a SPIR-V constant value.
GenerateU32Literal() was also creating an invalid AST - the type was U32, yet an an ast::SintLiteral was used.
Instead add Constant for holding a constant value, and use this as the map key.
This also removes the last remaining use of ast::NullLiteral, which will be removed in the next change.
