[MSPAINT] Allow paletteWindow to be bottom-aligned (#5216) 
The user will be able to move the palette window to bottom by dragging.
- Add Bar1ID registry setting.
- Move paletteWindow to top or bottom in mainWindow's WM_SIZE handling.
- Track the mouse dragging on paletteWindow.
- If the dragging is beyond the center point, then move paletteWindow.
