chore: Resolve tags in GROUP BY clause
Any `VarRef`s in the `Select` where the `data_type` field is `None`
indicates there is no field or tag found in the schema of any children
in the `FROM` clause

feat: Refactor node used to represent a tag in a `GROUP BY`
* Use `VarRef` for `Tag`, to ensure a consistent representation of a
  column reference across `GROUP BY`, `SELECT` projection and `WHERE`
  clause.
* Rename `tags` to `tag_names`
* `tags` now returns `VarRef`

chore: Introduce root `SelectQuery`
This is used to gather shared state for the query vs `Select`, which
represents state for each `SELECT` statement.

First example is tracking whether a statement projects multiple
unique measurements. This changed improved one of the plans, as it
no longer needs to sort the `iox::measurement` column.
