Support remaining Expr.is_<...> mask methods #3028
Description
Description
We have almost all of these supported, and completing that group seems pretty realistic to me.
They might all be possible with a default implementation in CompliantColumn (#2967) that just __invert__s another method?
is_not_null is the only one I'd push for being directly implemented for each backend for performance (see discord comment)
