Disable gestures on lockscreen

[Dlurak]

Is your feature request related to a problem? Please describe.
When locking the screen using hyprlock all gestures are still accepted and executed. This is especially problematic for killing the active window and even more for exec!

Describe the solution you'd like
There is already hyprgrass-bindm so how about following hyprlands naming scheme and introducing hyprgrass-bindl for gestures that also work on a lockscreen.

Describe alternatives you've considered

• Disabling all gestures on lock screens
  • Some gestures like changing the volume are nice on the lockscreen
• To prevent a change in behaviour of the current gestures create a new key hyprgrass-bindu for gestures that only work on an unlocked Hyprland. In my opinion it should be explicitly stated when a gesture works on the lockscreen rather then the other way around so I would prefer my first suggestion.
