Adding the option change Mesh Viewer

[classicrocker883]

Adding Mesh Viewer - change how the mesh is viewed

enables both options on how the mesh is viewed
with USE_UBL_VIEWER enabled, this gives a check box to alternate type of view for mesh

adding Menu Item
FILE--> dwin.cpp
under Draw AdvancedSettings Menu

  ```MENU_ITEM(ICON_MeshViewer, MSG_MESH_VIEW, onDrawSubMenu, DWIN_MeshViewer);  
  #if ENABLED(USE_UBL_VIEWER)
    EDIT_ITEM_F(ICON_PrintSize, "Change Mesh Viewer", onDrawChkbMenu, SetViewMesh, &BedLevelTools.view_mesh); 
  #endif```

//the function

    else

Be aware that this duplicates the code of the viewer, that is why I leave it only as a user's selectable at compile time.
Currently the RCT6 devices are close to the limit of the program's memory.

[classicrocker883]

i see, maybe that can be tweaked so it limit the memory

[classicrocker883]

using the RET6...

Without USE_UBL_VIEWER enabled
RAM: [== ] 23.3% (used 15300 bytes from 65536 bytes)
Flash: [==== ] 41.7% (used 218444 bytes from 524288 bytes)

With USE_UBL_VIEWER enabled
RAM: [== ] 23.4% (used 15304 bytes from 65536 bytes)
Flash: [==== ] 41.9% (used 219876 bytes from 524288 bytes)

Yes, RET6 doesn't have a problem because it has more program memory than RCT6, but many new printers are now with RCT6 and you could soft-brick those printers.
