gccrs: Use nr2.0 in typechecker

gccrs: Use nr2.0 in typechecker

I probably missed a few spots, but this should cover most of the type
checker.

gcc/rust/ChangeLog:

	* typecheck/rust-hir-type-check-expr.cc: Add includes.
	(TypeCheckExpr::visit): Use name resolver 2.0.
	(TypeCheckExpr::resolve_operator_overload): Likewise.
	(TypeCheckExpr::resolve_fn_trait_call): Likewise.
	* typecheck/rust-hir-type-check-path.cc
	(TypeCheckExpr::visit): Likewise.
	(TypeCheckExpr::resolve_segments): Likewise.
	* typecheck/rust-hir-type-check-type.cc
	(TypeCheckType::resolve_segments): Likewise.
	(ResolveWhereClauseItem::visit): Likewise.
	(TypeCheckType::visit): Avoid usage of
	Resolver::get_unit_type_node_id when handling TupleType, use
	name resolver 2.0 when handling QualifiedPathInType.

gcc/testsuite/ChangeLog:

	* rust/compile/nr2/exclude: Remove entries.
