Fix T60314: Missing strength w/ weight gradient

Typo fixes

Fix T59984: Drivers don't update values in UI or show proper errors

We now perform COW -> original data flushing for all the debug values + error
status flags on Drivers/DriverVariables/DriverTargets, as these are only set
when errors are encountered when evaluating drivers.

Properly clean up Python when exiting due to --python-exit-code

When BPY_python_end() is not called, there can be buffered data still in
`sys.stdout` or `sys.stderr`. This generally isn't an issue when those are
connected to a terminal, but when they are read by another process (in the case
of rendering with Flamenco, for example) we could miss the actual error message
that's causing the exit in the first place.

The following script demonstrates the issue; before this commit neither the
writes to STDERR and STDOUT nor the traceback of the NameError were shown.

#!/bin/bash

cat > file-with-errors.py <<EOT
import sys
print('THIS IS STDERR', file=sys.stderr)
print('THIS IS STDOUT', file=sys.stdout)
nonexisting.monkey = 3
EOT

blender --enable-autoexec -noaudio --background
any-existing-blendfile.blend
--python-exit-code 42
--python file-with-errors.py 2>&1 | cat
