ArmPkg/ArmSvcLib: Add ArmSvcLib implementation.

Browse Source 
This patch adds a library that enables invocation of SVCs from Exception
Level EL0. It will be used by the Standalone MM environment to request
services from a software running in a privileged EL e.g. ARM Trusted
Firmware. The library is derived directly from Arm SMC Library.
