Collections of inner validators for deep_iterable/deep_mapping

[AdrianSosic]

This is a copy of the first issue collected in #1206 to enable separate tracking of the bug.

The issue

Some of the inner validators accept lists while others still require the explicit use of and_. For consistency, I think all of them should ideally be able to handle lists. For the member_validator, the change has been in implemented in #925, but iterable_validator still struggles with lists. For example, the following piece of code works, but replacing any_ with a list will make it fail:

@define
class A:
    x: List[str] = field(
        validator=deep_iterable(
            member_validator=[instance_of(str), min_len(1)],
            iterable_validator=and_(instance_of(list), min_len(1)),
        ),
    )

For deep_mapping, lists/tuples not supported for any of its three arguments.
