gccrs: remove name resolution inserts from type-path

gccrs: remove name resolution inserts from type-path

We resolve path segments and inserted their resolution into the name
resolution space which was an old hack to use this as information in
code-gen/check-passes in order to help things move forward but this is
not nessecary

gcc/rust/ChangeLog:

	* typecheck/rust-hir-type-check-type.cc (TypeCheckType::visit): remove name resolution info
	(TypeCheckType::resolve_root_path): likewise
	* typecheck/rust-hir-type-check-type.h: likewise
