Making different fps-locker for Editor UI.

[Alexander-Kashapovich]

Now:
[physics/common/physics_ticks_per_second] uses for fps-lock in Script Editor.

UX problems:
With physsic fps < 30, editor badly reacting on mouse wheel rotate.

First of all, this setting not obvious.

Secondly, if project required low-fps physic, user must be work with 60fps in editor,and add line like "set_physic_fps(15)" in start of game. That increase editing artifacts in release project. Not bug, but unaffractively.

Proposal:
Make different fps-timer for all editor UI except scene-viewer and translate this setting in [interface/editor/...]

This is a bug that was fixed in 4.5.beta:

• Fix smooth scrolling being tied to physics process godot#104349

As a workaround for 4.4, add a feature tag override for editor_hint that sets physics_ticks_per_second to 60, so that the editor uses the default physics ticks per second value.

PS: There's already a general FPS limit in the editor, which can be configured by adjusting Low Processor Mode Sleep Usec in the Editor Settings.
