ArmPlatformPkg/PrePeiCore: add missing entries to AArch64 vector table
The PrePeiCore vector table for AArch64 mode is only half populated.
However unlikely, if exceptions from lower exception levels are ever
taken, they should be reported correctly, rather than causing a
recursive undefined instruction fault on the zero padding that was
introduced by commit SVN r18904 ("ArmPkg/ArmPlatformPkg: position
vectors relative to base"). So add the missing entries, and wire
them up to the default handler.
