Viewport used get_global_transform().xform_inv(mpos) to convert the mouse position to the control's local coordinates when getting the control's tooltip, which does not handle scale correctly. This impacted tooltips for any controls that depended on the position to determine what tooltip to show, including RichTextLabel, ItemList, Tree, and probably some others. This change is for Viewport to use get_global_transform_with_canvas().affine_inverse().xform(mpos) for tooltips instead, to match what we do for Viewport::_gui_call_input. Fixes godotengine#91984

Tested locally, it works as expected.
Testing project: RichTextLabelHintTestGdscript.zip
(This is the MRP from #91984 converted to GDScript, so you don't need a C# build to run it.)
