runtime: move mem profile sampling into m-acquired section It was not safe to do mcache profiling updates outside the critical section, but we got lucky because the runtime was not preemptible. Adding chunked memory clearing (CL 270943) created preemption opportunities, which led to corruption of runtime data structures. Fixes #47304. Fixes #47302.
