gccrs: [E0534] inline attribute was malformed

Inline attribute takes one argument, but
more than one argument was found.

gcc/rust/ChangeLog:

	* backend/rust-compile-base.cc (HIRCompileBase::handle_inline_attribute_on_fndecl):
	Added rich_location & error code.

gcc/testsuite/ChangeLog:

	* rust/compile/inline_2.rs: Added new case.
