Apply TypeCoercion rule before FilterPushDown

#3222 adds a new TypeCoercion rule. The rule is currently applied after filter push down but it could be beneficial to do this earlier. This is a follow on issue to do that work.

We need to implement #3414 first because of these test failures when moving the rule above filter push down:

failures:
    prune_decimal_eq
    prune_decimal_lt
    prune_int32_eq
    prune_int32_lt
    prune_int32_scalar_fun_and_eq
