gccrs: Refactor name resolver to take a Rib::ItemType

This allows us to track the type of declaration that is stored within a
Rib.

gcc/rust/ChangeLog:

	* resolve/rust-ast-resolve-expr.cc (ResolveExpr::visit): Add Rib argument.
	(ResolveExpr::resolve_closure_param): Likewise.
	* resolve/rust-ast-resolve-implitem.h: Likewise.
	* resolve/rust-ast-resolve-item.cc (ResolveTraitItems::visit): Likewise.
	(ResolveItem::visit): Likewise.
	* resolve/rust-ast-resolve-pattern.cc (PatternDeclaration::visit): Likewise.
	* resolve/rust-ast-resolve-pattern.h: Likewise.
	* resolve/rust-ast-resolve-stmt.h: Likewise.
	* resolve/rust-ast-resolve-toplevel.h: Likewise.
	* resolve/rust-ast-resolve-type.h: Likewise.
	* resolve/rust-name-resolver.cc (Rib::lookup_decl_type): Likewise.
	(Scope::insert): Likewise.
	(Resolver::insert_builtin_types): Likewise.
	* resolve/rust-name-resolver.h: Likewise.
