compiler: Fix racy ticker counter registration
Previously registration of ticky entry counters was racy, performing a
read-modify-write to add the new counter to the ticky_entry_ctrs list.
This could result in the list becoming cyclic if multiple threads
entered the same closure simultaneously.
Fixes #20451.
