sc: Fix menubar auto-accelerator behavior under gtk2

... when the focus is in the input field of the formula bar.
Regression of commit d90dcf3554a84b5600800ee6deb3cde879c62b8d
("tdf#113894 release ctrl of ctrl+v in input line should strip
formatting").

tdf#117017 Pasting into the formula bar shouldn't retain formatting

This is (kind of) regression from the previous commit
a860c94f0da22065074cc36e8ddda73261641533 ("tdf#117017 Make modifier
keys not trigger the InputChanged handler").

Reset of formatting when pasting into the formula bar via a keyboard
shortcut, was actually a side effect of the gtk auto-accelerator
work. In particual, bibisect (of the 5.2 cycle) points to commit
8d53d01f38b856f177aca3ed4d3cba3db10f24a5 ("tdf#96739: Send Ctrl-Left/
RightShift events to correct window"). The behavior was later changed
back with commit 0321dbb9be72f92c02919457cdc3c4e76cfbd11d
("Resolves: tdf#99324 let sidebar toggle auto-mnemonics on/off with
alt"), but introduced again upon request of tdf#113894, with commit
d90dcf3554a84b5600800ee6deb3cde879c62b8d ("tdf#113894 release ctrl of
ctrl+v in input line should strip formatting"). Now it's broken again
with the previous commit of this bug.

However, even if not retaining formatting is the desired behavior,
triggering it on a modifier key release isn't a good idea. So keep
the previous commit, and implement tdf#113894 differently. In
addition, make sure to get identical behavior regardless of the
pasting method, be it via a keyboard shortcut, a toolbar button or a
menu/context menu command. And users can still override this behavior
with the usual paste special dialog, or the toolbar dropdown.
