ArmPlatformPkg/PrePeiCore: constify PPI globals
Since PrePeiCore's .text section contains an AARCH64 exception
vector table, its 2 KB alignment propagates to other sections as
well. Since this is a SEC module, it should not have any writable
data in the first place, so change some non-const PPI globals to
const. The resulting binary has no .data section at all, which
saves 2 KB in the XIP image.
