[PassManager] Make passes inherit from RequiredPassInfoMixin/OptionalPassInfoMixin (#192120)
It's very easy to forget to add `isRequired() { return true; }` for
passes that must be run on all IR, rather than e.g. being skipped on
optnone functions.

This PR adds RequiredPassInfoMixin/OptionalPassInfoMixin which have
`isRequired()`, and the long term vision is there to be no default
`isRequired()` on PassInfoMixin.

However, for out-of-tree migration purposes, we leave a `isRequired() {
return false; }` for now in PassInfoMixin.
