In #1439 it became clear that there are a lot of cases where there is a TypeAdaptor validation in the codebase.

To ensure the resulting ValidationErrors are properly caught and re-raised with a dedicated error message, we should:

• create 2 wrappers which accept a TypeAdaptor object as the first object, the object to validate as the second argument....
• the first one would also a custom error class and custom error message as additional arguments. The wrapper will ensure all ValidationErrors are re-raised properly with custom errors
• the second one would have a third argument giving the default return value for what to do on a validation error.
• ban the TypeAdaptor.validate_python API via ruff config; inline ignore the violation for the two wrappers' use of it.
• Work through the ruff violations and replace them with the safe wrapper.

We should document the rationale - we want to ensure that all ValidationErrors are handled and do not propogate.
