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
FILE--> meshviewer.cpp

void MeshViewerClass::Draw(bool withsave /*= false*/) {
  Title.ShowCaption(GET_TEXT_F(MSG_MESH_VIEWER));
  #if ENABLED(USE_UBL_VIEWER)
  if(BedLevelTools.view_mesh) {
    DWINUI::ClearMainArea();
    BedLevelTools.viewer_print_value = true;
    BedLevelTools.Draw_Bed_Mesh(-1, 1, 8, 10 + TITLE_HEIGHT);}
    else
      DrawMesh(bedlevel.z_values, GRID_MAX_POINTS_X, GRID_MAX_POINTS_Y);
  #else
    DrawMesh(bedlevel.z_values, GRID_MAX_POINTS_X, GRID_MAX_POINTS_Y);
  #endif
  if (withsave) {
    DWINUI::Draw_Button(BTN_Save, 26, 305);
    DWINUI::Draw_Button(BTN_Continue, 146, 305);
    Draw_Select_Highlight(HMI_flag.select_flag, 305);
  }
  else
    DWINUI::Draw_Button(BTN_Continue, 86, 305);

  #if ENABLED(USE_UBL_VIEWER)
    if(BedLevelTools.view_mesh) {
      BedLevelTools.Set_Mesh_Viewer_Status();}
    else {
    char str_1[6], str_2[6] = "";
    ui.status_printf(0, F("Mesh minZ: %s, maxZ: %s"),
      dtostrf(min, 1, 2, str_1),
      dtostrf(max, 1, 2, str_2)
    );}
  #else
    char str_1[6], str_2[6] = "";
    ui.status_printf(0, F("Mesh minZ: %s, maxZ: %s"),
      dtostrf(min, 1, 2, str_1),
      dtostrf(max, 1, 2, str_2)
    );
  #endif

FILE--> settings.cpp

  #if ENABLED(USE_UBL_VIEWER)
    bool view_mesh;
  #endif

//under MarlinSettings::save()

  #if ENABLED(USE_UBL_VIEWER)
    EEPROM_WRITE(BedLevelTools.view_mesh);
  #endif

//under MarlinSettings:_load()

  #if ENABLED(USE_UBL_VIEWER)
    _FIELD_TEST(view_mesh);
    EEPROM_READ(BedLevelTools.view_mesh);
  #endif      

//under MarlinSettings:reset()

  #if ENABLED(USE_UBL_VIEWER)
    BedLevelTools.view_mesh = ENABLED(USE_UBL_VIEWER); //added mesh viewer option
  #endif 

FILE--> bedlevel_tools.cpp

//under

 
  #if ENABLED(USE_UBL_VIEWER)
    static bool viewer_asymmetric_range;
    static bool viewer_print_value;
    static bool view_mesh;
  #endif

FILE--> bedlevel_tools.h

  class BedLevelToolsClass {
public:
  #if ENABLED(USE_UBL_VIEWER)
    static bool viewer_asymmetric_range;
    static bool viewer_print_value;
    static bool view_mesh;
  #endif

Are you looking for hardware support?

No response

Describe the feature you want

This enabled two options of how the mesh is viewed for ProUI

Additional context

If this can somehow be simplified so it doesnt take so much memory having it duplicate the code

For accessible data visualization, a continuous color ramp is often preferable. See e.g. https://eagereyes.org/basics/rainbow-color-map . Some good diverging color maps can be found at https://www.kennethmoreland.com/color-maps/
