This attempts to fix a large regression introduced in #36343, which broke recursing values returned from `getter` Constraints, because they are now wrapped in in a `LazyProperty`. The `LazyProperty` needs to be evaluated because some checks are done on the type of `$value`, i.e `is_array` etc... in `validateGenericNode`.
I'm concerned that the original PR didn't really add sufficient test coverage for the introduction of `LazyProperty`, and I'm not 100% sure that I've caught all the cases where the `instanceof` check are needed in this PR.
For the tests, I added the `@dataProvider getConstraintMethods` to every test that hit the problem area of code.
~~The only issue is that my fixed has broken the test introduced in #36343, `testGroupedMethodConstraintValidateInSequence`.~~
~~I think I need @HeahDude to help me work through this. Maybe there is a more simple solution, one that doesn't require doing `instanceof LazyPropery` checks in multiple places, because this feels very brittle.~~
EDIT: fixed that test.
