Pass type information to `format_exception` from `transform_errors` for primitive types

[PIG208]

Description

In #258, __notes__ were added to support passing AttributeValidationNote and IterableValidationNote around. transform_errors uses these notes to pass the target type when calling format_exception. This works well in most cases, except for primitive types.

Feature Request

I want to be able to customize my format_exception function so that I know the exact target type of the exception without needing to inspect the error message. If I understand it correctly, in the current design, __notes__ is only set on exceptions that are raised when structuring an iterable or class, but is not for types like int, float and etc.
