Godot's "Emulate Mouse from Touch" setting is done on a per-project basis, but should be an editor setting.

Tested versions

Godot 4.4/b2b13d46c2fcd75502eec12c768caa23ee952900 (master as of Sep 28th).

System information

MacOS Sequoia, iOS

Issue description

Currently whether the emulate-mouse-input-from-touch setting (input_devices/pointing/emulate_mouse_from_touch) that is set for the Godot editor is derived from the project itself. The setting should govern the project itself, but should not govern the editor.

I believe that for the editor, it should always be set to true as there is little reason to not map touches to mouse events, and this setting should only be honored when running the user's game.

Steps to reproduce

Disable input_devices/pointing/emulate_mouse_from_touch on the project, restart Godot, and notice that the touch input no longer works.

Minimal reproduction project (MRP)
