Windows: no KEY_DOWN or CHAR events for the "Print Screen" / SYSRQ key -- does fire KEY_UP

[emersonrp]

Operating system: Windows 10 wxPython version & source: 4.2.1, from wxpython.org Python version & source: 3.11.8, from python.org

Description of the problem:

On Windows (10 at least, probably others), the Print Screen / SysRq key doesn't fire a key-down or char event at all. It does fire a key-up event when released. This can be seen by running the Key Events section of the wxpython demo.

Windows Settings > Ease of Access > Keyboard > "Print Screen shortcut" is off.

(This is still true in Windows 11, FWIW, with Python 3.13.1 and wxPython 4.2.2.)
