RFR: 8360647: [XWayland] [OL10] NumPad keys are not triggered [v2]

[Alexander Zvegintsev]

> When we try to pass `XK_KP_0` to [`NotifyKeyboardKeysym`](https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.RemoteDesktop.html#org-freedesktop-portal-remotedesktop-notifykeyboardkeysym) in Remote Desktop API, it presses/releases `SHIFT` + `XK_KP_Insert`.
> 
> To get the same result as XTest api when using `NotifyKeyboardKeysym` we should use `XK_KP_Insert` instead of `XK_KP_0` regardless of NumLock state. Similarly for other Numpad keys.

Alexander Zvegintsev has updated the pull request incrementally with one additional commit since the last revision:
