Prune remaining unused package dependencies. (#4273)

## Issue

Follow-on from
#4270.

## Description

This PR:

1. Adjusts `cabal.project` so that `cabal build` will fail with an error
if there are any unused package dependencies in any package. (See
23873fd.)
2. Removes all remaining unused package dependencies from all packages.
