ArmPlatformPkg: Create an ARM Platform DSC / FDF / ArmPlatformLib template

By copying these templates, it should make easier to port EDK2 to new ARM
Platforms.

- ArmPlatformPkg.(dsc|fdf): For EDK2 firmwares which support the full boot
story from cold boot to OS loading
- ArmPlatformPkg-2ndstage.(dsc|fdf): For EDK2 as a second stage boot loader
(either started after a proprietary ROM firmware or x-loader)
