Make type import/export API Annotation friendly
Summary:
At the moment an export of the form
type C(..)
is parsed by the rule
```
| 'type' oqtycon {% amms (mkTypeImpExp (sLL $1 $> (unLoc $2)))
[mj AnnType $1,mj AnnVal $2] }
```
This means that the origiinal oqtycon loses its location which is then retained
in the AnnVal annotation.
The problem is if the oqtycon has its own annotations, these get lost.
e.g. in
type (?)(..)
the parens annotations for (?) get lost.
This patch adds a wrapper around the name in the IE type to
(a) provide a distinct location for the adornment annotation and
(b) identify the specific adornment, for use in the pretty printer rather than
occName magic.
