Fix an issue with aync copy timestamps

The timestamps coming from the HIP runtime for asynchronus memory
copies are corrupted (begin > end) because the HSA setting to record
timestamps is turned off by the tracer's HSA intercept.

The solution is to intercept hsa_amd_profiling_async_copy_enable and
remember the application/runtime's request so that it can be ORed with
IsEnabled(ACTIVITY_DOMAIN_HSA_OPS, HSA_OP_ID_COPY).
