Subject: Continue Caps Word when AltGr (right Alt) is held. (#17156)

This is a minor bug fix for Caps Word. Currently, Caps Word turns off
whenever a non-shift mod becomes active. This is done to avoid
interfering with hotkeys.

This commit makes an exception to continue Caps Word when AltGr (right
Alt) is held. Outside the US, the AltGr key is used to type additional
symbols (https://en.wikipedia.org/wiki/AltGr_key). Depending on the
language, these may include symbols used within words like accented
letters where it would be desirable to continue Caps Word.
