Over the years the users guide's language extension documentation has
gone through quite a few refactorings. In the process some of the
descriptions have been rendered non-sensical. For instance, the
description of `NoImplicitPrelude` actually describes the semantics of
`ImplicitPrelude`.
To fix this we:
* ensure that all extensions are named in their "positive" sense (e.g.
`ImplicitPrelude` rather than `NoImplicitPrelude`).
* rework the documentation to avoid flag-oriented wording
like "enable" and "disable"
* ensure that the polarity of the documentation is consistent with
reality.
Fixes #23895.

The implementation of `checkHomeUnitsClosed` was traversing every single path
in the unit dependency graph - this grows exponentially and quickly grows to be
infeasible on larger unit dependency graphs.
Instead we replace this with a faster implementation which follows from the
specificiation of the closure property - there is a closure error if there are
units which are both are both (transitively) depended upon by home units and
(transitively) depend on home units, but are not themselves home units.
To compute the set of units required for closure, we first compute the closure
of the unit dependency graph, then the transpose of this closure, and find all
units that are reachable from the home units in the transpose of the closure.

Previously, the logic for checking if a data constructor needs a wrapper or not
would take into account whether the constructor's fields have explicit
strictness (e.g., `data T = MkT !Int`), but the logic would _not_ take into
account whether `StrictData` was enabled. This meant that something like `type
data T = MkT Int` would incorrectly generate a wrapper for `MkT` if
`StrictData` was enabled, leading to the horrible errors seen in #24620. To fix
this, we disable generating wrappers for `type data` constructors altogether.
Fixes #24620.
