Make ets:insert/2 and ets:insert_new/2 yield

The `ets:insert/2` and `ets:insert_new/2` functions did not yield even
when they were given long lists and a call to one of the functions did
only consume a single reduction. This commit fixes these problems.

The fix uses the "Yielding C Fun" tool to automatically generate
yieldable versions of C functions.
