System information

Godot v4.2.1.stable - Windows 10.0.19045 - GLES3 (Compatibility) - NVIDIA GeForce RTX 2060 (NVIDIA; 31.0.15.3179) - Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz (12 Threads)

Issue description

In the inspector for a NavigationPolygon in a NavigationRegion2d node the hints for 3D physics layers are displayed in the Parsed Collision Mask attribute.
As the 2D physics layers are used to scan for colliders anyways, It would be expected to show hints for the 2D physics layers instead of 3D physics layers.

The issue seems to be with this line (on master-branch):

godot/scene/resources/navigation_polygon.cpp

Line 504 in 4e990cd

ADD_PROPERTY(PropertyInfo(Variant::INT, "parsed_collision_mask", PROPERTY_HINT_LAYERS_3D_PHYSICS), "set_parsed_collision_mask", "get_parsed_collision_mask");

I will try to create a fix myself.

Steps to reproduce

1. Create a New Project
2. In the project settings: Layer Names -> 2D Physics: give layer 1 the name "2d_layer_1"
   
3. In 3D Physics: give layer 1 the name "3d_layer_1"
4. In 2d Editor create Root Node: 2D Scene
5. Append a New Node: NavigationRegion2D
6. In the Inspector of the NavigationRegion2D create a new Navigation Polygon
7. Expand the Navigation Polygon and hover layer 1of the parsed Collision Mask property
   
   "3d_layer_1" is displayed
   Expected behavior would be that "2d_layer_1" is displayed.
