PyAPI: support retrieving the exception when running a string

- Optionally get the error as a single line.
- Support access the error as an allocated string.
- PyC_ExceptionBuffer_Simple was always printing to the `stdout` while
  PyC_ExceptionBuffer didn't, now either print to the output.

Without this, callers are unable to do anything with the error string.
