Debugger: MemoryView - Tweak target address drawing.

- Since we actually draw a selection now, change the target address
  highlight to clearly distinguish it. Rather than inverting it, it's
  now drawn with a normal background and red text in the hex display.
  The text mode subcomponent still shows it as an invert though, since
  the latter doesn't currently indicate the selection.
