sw: don't copy useless char escapement to next node on split

Unless autocorrect notices such a just-typed content, pressing enter at
the end of a paragraph which ends with superscript or subscript text
will carry over that formatting to the next paragraph, which is hardly
wanted by any user. Technically this is not copying: paragraph split
works by creating a next text node, moving all content & formatting to
this next node, then move part of the content back to the previous node,
which is all content in case of an enter at the end of a paragraph.

Copying character formatting over to the next text node makes sense:
e.g. paragraph alignment or boldness is probably something a user wants
to continue using in the next text node. But superscript is typically
created by autocorrect in English text for "1st" and similar input, this
is usually unwanted in the next paragraph.

Fix the problem by special-casing the RES_CHRATR_ESCAPEMENT case and
remove the matching SvxEscapementItem from the hints of the just created
next paragraph in case it's there.

A possible future improvement would be to support this when there are
other active (direct formatting) hints, in which case going via
SwDoc::ResetAttrs() is probably a better choice, but the effects of that
for undo and redlining is not clear.
