add block kind during name resolution

[bvanjoi]

cc #143141 (comment)

I've discovered we cannot completely remove RibKind::Module as it's still required for module scope operations and is more semantically appropriate, such as:

rust/compiler/rustc_resolve/src/late.rs

Lines 1529 to 1540 in cd43430

	fn with_mod_rib<T>(&mut self, id: NodeId, f: impl FnOnce(&mut Self) -> T) -> T {
	let module = self.r.expect_module(self.r.local_def_id(id).to_def_id());
	// Move down in the graph.
	let orig_module = replace(&mut self.parent_scope.module, module);
	self.with_rib(ValueNS, RibKind::Module(module), |this| {
	this.with_rib(TypeNS, RibKind::Module(module), |this| {
	let ret = f(this);
	this.parent_scope.module = orig_module;
	ret
	})
	})
	}

Ha, I assumed it's already night at your time zone so I started working on this myself.
Let me finish the work, I also want to fix some pre-existing bugs when Normal and Module for blocks weren't treated in the same way.

Got it, closing it.
