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.
