gccrs: Change early resolver visit_attributes arguments

We do not need to copy the whole vector we can simply take a reference
instead.

gcc/rust/ChangeLog:

	* resolve/rust-early-name-resolver-2.0.cc (Early::visit_attributes):
	Change argument to reference.
	* resolve/rust-early-name-resolver-2.0.h: Update function
	prototype.
