Explicitly pass `binding` every time we parse `Id`
Explicitly pass `binding` every time we parse `Id`

Added `binding_id` instead of `id` to function names and
added explicit `binding: bool` parameter to `id` parsing and
construction functions to ensure that it's hard to miss
and parse wrong kind of `Id`.
