* MSW specific: Dark Mode: First implementation

* Use menu instead of NoteBook

* Implemented MessageDialog
+ Fixed DarkMode for all dialogs and ColorPicker

* MSW DarkMode: Added missed updates for the switching between modes

* MSW DarkMode: Updated all existed context menus after switching of the mode
+ Added markers for the menu item witch is related to the selected tab

* Used wxFrame instead of wxDialog for SettingsDialog
(this change allow us to use menu bar in SettingsDialog)

+ fix for #6548 - Prusa Slicer 2.3.1 not activating non-modal settings window if settings window is minimized

* Implemented "Always use Dark mode colors" preference option

* Fixes for non_MSW build

* Next fixes for non-MSW builds

* Preferences: Fixed selection of the Settings Layout for non-MSW platforms
+ Updated DarkMode for colorpickers

* Windows DarkMode next fixes

* MSWDarkMode: Suppress to use system color to the PrusaSlicer
Select "Preferences -> Use Dark color mode (experimental)" to allow dark mode for the application

* Fixed MSW build

* MSWDarkMode: Upadteed color mode for ExtruderSequenceDialog and for dialogs related to the DoubleSlider

* Implemented Auto recreation of the PrusaSlicer when color mode is changed.

* Preferences: Added option "Set settings tabs as menu items (experimental)"
