Clemens Backes 068536f109 [wasm] Remove thread timings (CPU time) 
On Mac, we spend around 30% of lazy compile time in {ThreadTicks::Now}.
On Linux it's less severe, but still around 10%.
That's too much overhead for measurements that only show up in UKM, so
remove that.

The unused fields will be removed from the UKM events after the plumbing
on the chromium side has been removed.
