Resolves #115090, where exceptions from the text editor called
`sys.excepthook` in v3.6 but not in v4.0.
The error was caused by PyC_ExceptionBuffer calling PyErr_Display
instead of PyErr_Print.
While technically a regression in [0], the behavior in 3.6x wasn't
working properly either since a user-defined `sys.excepthook` could
prevent PyC_ExceptionBuffer from accessing the exception text.
Resolve with the following changes:
- BPy_errors_to_report has been updated not to print errors.
Previously BPy_errors_to_report would *sometimes* print the error,
which complicated situations where the caller wanted predictable
behavior (always printing or never printing).
- `PyErr_Print()` must be used to display errors to the output,
this will call `sys.excepthook` as it used to.
It's better not to rely on side effects of BPy_errors_to_report()
for error handling.
