sw_redlinehide_4b: tdf#113479 SetRedlineFlags() calls no longer...

...able to be triggered by the UI, so the performance problem should be
gone.

The SwXTextDocument "ShowChanges" property allows API clients to call
SetRedlineFlags() and change the model; this API should be retained
as-is for now, because there is no way currently (outside of the rather
specialised a11y API) to get a "merged view" of the paragraphs in the
document, so API clients may want to (temporarily) toggle this property
to then retrieve properties from the model.  In case we later find that
there are no API clients that want to do such things, the property can
be removed.

A run with assert() instead of SAL_WARN_IF() found only 2 tests that
explicitly call SetRedlineFlags() to clear ShowDelete.
