gccrs: testsuite: Add tests for pub items in proc_macros

Crates of type 'proc-macro' should not have any other pub member than
procedural macros. These new test will avoid regression on error
messages in such sitation.

gcc/testsuite/ChangeLog:

	* rust/compile/proc_macro_pub_function.rs: New test.
	* rust/compile/proc_macro_pub_module.rs: New test.
