Fix more types (#19333)

* Migration::upsert() returns void

* Unneeded `@property` tags

* Add missing `null` param/return types

* Null types for db\Query + db\ActiveQuery

* Fixed testSelect

* Null types for Validator

* Several more null types

* One more

* Make AccessRule::$allow always a boolean

It doesn't have any special null handling, so it's safe to default to false

* Validator::$skipOnEmpty is always a boolean

* Catch all throwable from Widget::widget()

* Don't limit $previous args to \Exception

The actual \Exception allows $previous to be any throwable in PHP 7+

* Add Throwable catch block to Instance::get()

* Throwable cleanup

Comment changes only.

- Document \Throwable instead of \Exception wherever appropriate
- Removed redundant exception/error classes when \Throwable is referenced

* Yii::setlogger() accepts null

* ArrayHelper::removeValue() can remove any type of value

* Change default $allow value to false
