gccrs: [E0268] break or continue used outside of loop

Refactored error description similiar to rustc.

gcc/rust/ChangeLog:

	* typecheck/rust-hir-type-check-expr.cc (TypeCheckExpr::visit):
	refactored and call error function.

gcc/testsuite/ChangeLog:

	* rust/compile/break1.rs: Modified to pass test case.
	* rust/compile/continue1.rs: likewise.
	* rust/compile/break_continue_outside_loop.rs: New test.
