Python: Print script errors with CLOG

Currently, when a python error is encountered when rendering the UI, the
corresponding message is printed to stdout / stderr via `PyErr_Print`,
this patch modifies behavior so that a cursory message is also printed
with CLOG

This has the benefit of allowing for testing via
`--debug-exit-on-error`, which aborts Blender when an error message is
printed.
