Add tooltip for in-editor FPS display in 3D viewport

Also enhance Control/Label documentation about tooltips and mouse filter,
as it took me a while to understand why Labels didn't show tooltips.

Closes #26082.

 		[b]User Interface nodes and input[/b]
 		Godot sends input events to the scene's root node first, by calling [method Node._input]. [method Node._input] forwards the event down the node tree to the nodes under the mouse cursor, or on keyboard focus. To do so, it calls [method MainLoop._input_event]. Call [method accept_event] so no other node receives the event. Once you accepted an input, it becomes handled so [method Node._unhandled_input] will not process it.
 		Only one [code]Control[/code] node can be in keyboard focus. Only the node in focus will receive keyboard events. To get the focus, call [method grab_focus]. [code]Control[/code] nodes lose focus when another node grabs it, or if you hide the node in focus.
-		Set [member mouse_filter] to MOUSE_FILTER_IGNORE to tell a [code]Control[/code] node to ignore mouse or touch events. You'll need it if you place an icon on top of a button.

 		[Theme] resources change the Control's appearance. If you change the [Theme] on a [code]Control[/code] node, it affects all of its children. To override some of the theme's parameters, call one of the [code]add_*_override[/code] methods, like [method add_font_override]. You can override the theme with the inspector.

 		Label displays plain text on the screen. It gives you control over the horizontal and vertical alignment, and can wrap the text inside the node's bounding rectangle. It doesn't support bold, italics or other formatting. For that, use [RichTextLabel] instead.
-		Note that contrarily to most other [Control]s, Label's [member Control.mouse_filter] defaults to MOUSE_FILTER_IGNORE (i.e. it doesn't react to mouse input events).
+		Note that contrarily to most other [Control]s, Label's [member Control.mouse_filter] defaults to MOUSE_FILTER_IGNORE (i.e. it doesn't react to mouse input events). This implies that a label won't display any configured [member Control.hint_tooltip], unless you change its mouse filter.
