Cherry-pick of #13491
This change includes the rule addition and mostly manual changes to existing code in order to bring it in line with the new rules and avoid as many ignores as is reasonable.
I added a number of {{from err}} statements to the end of exceptions that currently include the error message. The error message being included in the raised string can be removed later, but keeping for consistency for now.
In cases where I raised from None, the raised exception is clear enough that the additional context of the parent exception isn't helpful.
fixes #13690
