gccrs: [E0423] expected function, tuple struct or tuple variant, found struct

Give error when an identifier was used like a function
name or a value was expected and the identifier exists
but it belongs to a different namespace.

gcc/rust/ChangeLog:

	* typecheck/rust-tyty-call.cc (TypeCheckCallExpr::visit):
	called error function.

gcc/testsuite/ChangeLog:

	* rust/compile/found_struct.rs: New test.
