[python-experimental] simplifies type checking (#13437)

* Better control of when to write MetaOapg

* Makes MetaOapg in Schema a type hint rather than assignmnet

* Samples regenerated

* Adds tuple types

* Removes types info

* Adds _types

* Samples regenerated

* Adds missing mixins, samples regenerated

* SchemaTypeChecker removed

* Samples regnerated

-        Runs all schema validation logic and

-        returns a dynamic class of different bases depending upon the input
+        If those validations passed, the validated classes are collected in path_to_schemas
-        This makes it so:
-        - the returned instance is always a subclass of our defining schema
-            - this allows us to check type based on whether an instance is a subclass of a schema
-        - the returned instance is a serializable type (except for None, True, and False) which are enums
-
-        Use cases:
-        1. inheritable type: string/decimal.Decimal/frozendict.frozendict/tuple
-        2. singletons: bool/None -> uses the base classes BoolClass/NoneClass
-
-        Required Steps:
-        1. verify type of input is valid vs the allowed _types
-        2. check validations that are applicable for this type of input
-        3. if enums exist, check that the value exists in the enum

-        Runs all schema validation logic and

-        returns a dynamic class of different bases depending upon the input
+        If those validations passed, the validated classes are collected in path_to_schemas
-        This makes it so:
-        - the returned instance is always a subclass of our defining schema
-            - this allows us to check type based on whether an instance is a subclass of a schema
-        - the returned instance is a serializable type (except for None, True, and False) which are enums
-
-        Use cases:
-        1. inheritable type: string/decimal.Decimal/frozendict.frozendict/tuple
-        2. singletons: bool/None -> uses the base classes BoolClass/NoneClass
-
-        Required Steps:
-        1. verify type of input is valid vs the allowed _types
-        2. check validations that are applicable for this type of input
-        3. if enums exist, check that the value exists in the enum
