Clemens Backes 03ad044ce5 [fuzzer][liftoff] Account for locals in max_steps 
The fuzzer limits the number of "steps" that should be executed in
Liftoff. A "step" typically means one Wasm instruction. The cost of
function calls is linear in the number of parameters and locals though,
so that should be accounted for.

In the linked issue (timeout), we were repeatedly calling a function
with a big number of reference locals, which all need to be initialized
to the null value.
