[arch][arm64] Set up early boot exception handlers During early boot, we might not have a stack or other context set up for the actual exception handlers. In that small window, we now redirect all exceptions to platform_early_halt to exit somewhat cleanly to non-secure instead of looping infinitely in case an exception occurs. Test: injected an invalid memory access into early_mmu.c Bug: 223900674 Change-Id: I6b9490b8e5138f174e93188650a40de5af3f3488
