Add a new 'Target' to the ast::CallExpression, which can be either an Identifier or Type. The Identifier may resolve to a Type, if the Type is a structure or alias. The Resolver now resolves the CallExpression target to one of the following sem::CallTargets: * sem::Function * sem::Intrinsic * sem::TypeConstructor * sem::TypeCast This change will allow us to remove the type tracking logic from the WGSL parser, which is required for out-of-order module scope declarations.
