Support QuasiQuotes scoping

For example, when using `reldir` QuasiQuoter from [`path`](https://www.stackage.org/package/path) library like this:

```haskell
{-# LANGUAGE QuasiQuotes #-}

module Sandbox where

import Path (reldir)

foo = [reldir|aba|]
```

I get `Scoped None` but expecting `GlobalSymbol (Value "Path" "reldir") ...` or something like that.
