ArmPlatformPkg: Add support for PrePi module

This module is enabled for ArmRealViewEb and ArmvExpress builds
when the macro EDK2_SKIP_PEICORE is passed to the build system.

The PrePi module can be used when the DRAM has already been initialized
by the SEC phase/1st stage boot loader and no call to external PEIM is
required.
