There were several bugs in the vector table relocation code which means it can't really have been used by anyone on AArch64 in the last decade or so. So delete the support code from the library, as well as the ArmRelocateExceptionLib.inf file. This gets rid of PcdDebuggerExceptionSupport (including a duff reference in CpuDxe), PcdCpuVectorBaseAddress and PcdRelocateVectorTable. Signed-off-by: Leif Lindholm <leif.lindholm@oss.qualcomm.com>
