Issue description

I've got a warning today which is:

Godot Engine v4.5.dev5.official (c) 2007-present Juan Linietsky, Ariel Manzur & Godot Contributors.
--- Debug adapter server started on port 6006 ---
--- GDScript language server started on port 6005 ---
ERROR: modules/navigation_2d/2d/nav_map_builder_2d.cpp:150 - Navigation map synchronization error. Attempted to merge a navigation mesh polygon edge with another already-merged edge. This is usually caused by crossing edges, overlapping polygons, or a mismatch of the NavigationMesh / NavigationPolygon baked 'cell_size' and navigation map 'cell_size'. If you're certain none of above is the case, change 'navigation/3d/merge_rasterizer_cell_scale' to 0.001.

The line 140 (in the head) of the source is:

ERR_PRINT_ONCE("Navigation map synchronization error. Attempted to merge a navigation mesh polygon edge with another already-merged edge. This is usually caused by crossing edges, overlapping polygons, or a mismatch of the NavigationMesh / NavigationPolygon baked 'cell_size' and navigation map 'cell_size'.

I guess the author just made a copy & paste a bit too quickly and forgot to replace 3 by 2 in '3d' (in 'navigation/3d/merge_rasterizer_cell_scale') as it doesn't make much sense to modify something 3D related to fix an issue with a 2D "thingy".

Steps to reproduce

I don't know what exactly cause the issue but it not longer occurs in recent projects I used.

Minimal reproduction project (MRP)

In this case the very msg still makes sense because there is no 2D projectsettings for it.

What does not make sense is that the 2d part does not use it anymore ever since it was split off from the NavigationServer3D.

That the NavigationServer2D exists on its own is just recently a thing in Godot 4.5. Before it used the same 3d server behind the scene.

I guess the cleanest option is to add the setting to the ProjectSettings for 2D and update the World2D navigation map init to also use that setting for the created Viewport default 2d navigation map.

I'm interested in taking this Issue :>, it'll be my first contribution to Godot btw.

I basically did the same thing as 3d implementation but for 2d one and waiting for github action to succeed.

(edit: also added the binding methods map_set_merge_rasterizer_cell_scale and map_get_merge_rasterizer_cell_scale)
