32f400a4 - [ty] Make auto-import ignore symbols in modules starting with a `_`

[ty] Make auto-import ignore symbols in modules starting with a `_` This applies recursively. So if *any* component of a module name starts with a `_`, then symbols from that module are excluded from auto-import. The exception is when it's a module within first party code. Then we want to include it in auto-import.
