New API to read Caps-Lock and Num-Lock state

For JavaFX 17, I am planning to add a minor enhancement to read the
state of the keyboard lock keys, specifically, Caps-Lock, Num-Lock, and
maybe Scroll-Lock (although I might defer the latter to a future version
since it will be more difficult to test, and doesn't seem as useful).
This is currently tracked by JDK-8259680 .
The proposed API would be something like:
public static boolean Platform::isKeyLocked(KeyCode keyCode);
One question is whether we should throw an exception if the key state
cannot be read on a particular system (e.g., Num Lock on macOS), which
is what the similar AWT API does. I don't have a strong opinion on that
poont, although I wouldn't want to throw an exception if the keyboard
doesn't have the key in question, as long the system is able to read the
Comments are welcome.
