Fixed ARMv8 SMP time sources (#555)
Follow up on the issue-541 execution profiling work. PR #553 fixed SMP execution profile total-time aggregation, and PR #554 fixed Armv7/R SMP timestamp hooks that used decrementing private timers.
This change addresses the remaining related gap in ARMv8-A SMP ports: their timestamp hooks returned zero, which left execution profiling and trace timestamps without a progressing time source. Replace those stubs with the architectural generic physical counter, CNTPCT_EL0, across the ARMv8-A SMP GNU, AC6, IAR, and GHS variants.
The local ARMv8 AArch64 system timer example already uses CNTPCT_EL0 for physical count reads, so this keeps the SMP timestamp hook aligned with the existing port examples while preserving the 32-bit ULONG return contract.
