ArmVirtPkg: store separate console and debug PL011 addresses in GUID HOB

Browse Source 
PlatformPeiLib produces the EarlyPL011BaseAddress GUID HOB, and
FdtPL011SerialPortLib consumes it. Extend the HOB such that it also carry
the base address of the PL011 UART meant for DebugLib usage -- namely the
first UART that is *not* designated by the /chosen node's "stdout-path"
property. Implement this policy in PlatformPeiLib.

Note that as far as the SerialPortLib+console UART is concerned, this
patch makes no difference. That selection remains consistent with the
pre-patch state, and therefore consistent with EarlyFdtPL011SerialPortLib.
