gui : Allow changing vertical alignment of status bar icons

- If the var TW_STATUS_ICONS_ALIGN can be set to:
   1) 'center' or '2' to center-align the icons/text (vertically)
   2) 'bottom' or '3' to bottom-align the icons/text (vertically)
  ( Value calculated by utilizing statusbar height & size of font_m ).
- If set to anything else or not set at all, it falls back to twrp's
  old behaviour of top-aligning the status bar icons.
