* fix: check only first sublevel for validators with `each_item`
When using a validator with `each_item`, the items are all validated
one by one. But if the items are also iterable the subitems would then
be validated because the validator would be kept as it is.
Now the validator passed to the items is changed and won't be propagated
closes#1933
* chore: add breaking change
* fix: ensure to always return one of the values in `Literal` field type
closes#2166
* perf: improve `literal_validator` speed
Thanks to @yobiscus
* fix: when more options in Literal
switch from `set` to `dict` to still have a O(1) complexity
Thanks @layday :)
Following #2000 and #2046 we can't `pop` the current value when assigning
a new one (which was probably the most efficient) as we want to keep the
order in the `__dict__`.
So let's do a shallow copy of the `__dict__` without the current value
fix#2073
* don't pop the value off __dict__
* adding change description
* still pop the field, but catch any exc, set the field to og value, and reraise exc
* adding tests
* fixing test
* improve tests/test_validators.py tests

* call validator with correct "values" type in BaseModel.__setattr__
* Fix code review comments
- use `self.__dict__` as the values parameter
- refine changed markdown
