ArmVirtPkg: increase memory preallocations for secure build

ArmVirtPkg: increase memory preallocations for secure build

This is a followup to r17554 ("ArmVirtPkg: increase memory
preallocations to reduce region count") that increases the sizes
of the preallocated regions to account for the footprint of the
crypto and authentication libraries. This is only done if secure
boot is enabled at build time, to prevent imposing a larger minimum
RAM size on non-secure builds.
