cmSystemTools: Fix 'ErrorOccurred' spelling

Rename the booleans 's_ErrorOccured' and 's_FatalErrorOccured' to
's_ErrorOccurred' and 's_FatalErrorOccurred', respectively.

Rename the getters and setters to 'Get[Fatal]ErrorOccurred' and
'Set[Fatal]ErrorOccurred', and fix all uses across the codebase.
