feat: add lcAny constant to Prelude (#6665)

Browse source 
This PR adds a new lcAny constant to Prelude, which is meant for use in
LCNF to represent types whose dependency on another term has been erased
during compilation. This is in addition to the existing lcErased
constant, which represents types that are irrelevant.
