Subject: ArmPlatformPkg: create hw-agnostic LcdGraphicsOutputDxe driver

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.

[ardb: add it to ArmPlatformPkg.dsc so we can build test it standalone]
