Convert `App.Control.Exception` interface to an alias to `HasErr`.
Probably `Exception` interface need to be deprecated or removed.
Note similar problem exists with `PrimIO` calling `PrimIO, Exception`,
also need to be fixed.
Fix this scenario:
```
throwBoth : Has [Exception String, Exception Int] es => App es ()
throwOne : Has [Exception Int] es => App es Int
throwOne {es} = handle {err = String} {e = es} throwBoth (\r => pure 1) (\e => pure 3)
```
With this commit it works, before this commit it failed with:
```
Error: While processing right hand side of throwOne. Can't find an implementation for Exception Int (String :: es).
