Revert "Data.List specialization to []"
This reverts commit bddecda1a4c96da21e3f5211743ce5e4c78793a2.
This implements the first step in the plan formulated in #20025 to
improve the communication and migration strategy for the proposed
changes to Data.List.
Requires changing the haddock submodule to update the test output.
