This is second part needed for #17819.
There is already binding in default bindings: `"menu":
"editor::OpenContextMenu",` (but won't work on windows without this
change)
Release Notes:
- Handle "menu" key in windows
Closes#24744
and should also fix#17819
The change is split into two commits, first one adds F10 handling (it
needs to be handled inside `parse_syskeydown_msg_keystroke`, the second
one properly handles `Alt+Fn` combinations, this also needs to happen in
`parse_syskeydown_msg_keystroke` and is similar to a fragment inside
`parse_keydown_msg_keystroke`
Release Notes:
- Fixes F10 and Alt+Fn handling on windows
