Create a new LcdGraphicsOutputDxe driver from the existing sources that
takes its hardware abstractions from a LcdHwLib library instance rather
than from a .c file linked directly. All we need is a new .inf file, and
a minimal tweak to LcdGraphicsOutputDxe.h to reuse the LcdHwlib prototypes
rather than open code them.
