Subject: ArmPlatformPkg: Introduce ArmPlatformSysConfigLib

The purpose of this library is to create an interface to communicate
with the platform micro-controller.
It abstracts the communication protocol (eg: SPI, UART, etc) between
the application processor and the micro-controller.

ArmPlatformPkg/ArmVExpressPkg: Implement ArmPlaformSysConfigLib

This implementation allows to communicate with the microcontroller of the
Versatile Express motherboard.
