Do not parse ->/lambda unless --uf-ho enabled (#4544)
Fixes #4477. Logic ALL includes higher-order but we currently do not
support solving higher-order problems unless --uf-ho is enabled. This
commit changes the condition under which we parse -> and lambda to
only enabled parsing of those symbols if the logic allows higher-order
constraints and --uf-ho is enabled.
