gccrs: [E0535] Unknown argument given to inline attribute

The inline attribute only supports two arguments:
 - always
 - never
All other arguments given to the inline attribute will
return error.

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 message.
