Remove redundant needsFrame & allow frame schedule skipping on mouse move

[UjinT34]

• Removes needsFrame = true before scheduleFrame since it is set inside. Useful for logging needsFrame changes.
• Adds optional skipShedule argument to moveCursor to allow cursor:no_break_fs_vrr with hw cursors

skipShedule requires HL updates to be useful. Just passing true to moveCursor is not enough to fix VRR. Probably needs something like https://github.com/hyprwm/Hyprland/pull/6877 for hw cursors.

It is not guaranteed that the cursor position will be updated to the correct value when something finally decides that the frame should be rendered. Something needs to update the cursor position between frames without triggering extra frames. I think it's easier to skip frame schedule than to call an extra moveCursor under complex conditions. Not moving the cursor will definitely solve the VRR issues but that's not what humans want. They can't keep their hands off the mouse and tend to get disappointed when their cursor is stuck in place %)
