Fuzzing: add use_egraphs option back to fuzzing config generator. (#5388)

Browse Source 
This PR reverts #5128 (commit b3333bf9ea),
adding back the ability for the fuzzing config generator to set
the `use_egraphs` Cranelift option. This will start to fuzz the
egraphs-based optimization framework again, now that #5382 has landed.
