tdf#126085: Enable Ctrl+Comma & Ctrl+Shift+Comma with European layouts

Also: tdf#127726, tdf#130073

As many European layouts don't have a semicolon key (";" is instead produced
by Shift+Comma), map .uno:InsertCurrentDate and .uno:InsertCurrentTime to
Ctrl+Comma and Ctrl+Shift+Comma, respectively.

The list of locales is based on information about national keyboard layouts
from Wikipedia (mostly https://en.wikipedia.org/wiki/QWERTY).
