ArmPkg: Convert PcdMonitorConduitHvc to FixedAtBuild 

Feature PCDs and fixed-at-build PCDs are identical in concept, but the
latter are accessible from assembler, whereas the former are not. So
convert the SMCCC conduit selection PCD to fixed-at-build so we can make
use of this in a subsequent patch.
