Rhys Hiltner 2c0a9884e0 runtime: add CPU samples to execution trace
When the CPU profiler and execution tracer are both active, report the
CPU profile samples in the execution trace data stream.

Include only samples that arrive on the threads known to the runtime,
but include them even when running g0 (such as near the scheduler) or if
there's no P (such as near syscalls).

Render them in "go tool trace" as instantaneous events.

For #16895
