Summary: Tiny PR to add the `experimental_allow_mempurge` to the `db_bench` tool (`Mempurge` is the current prototype for memtable garbage collection). This is useful to benchmark the prototype of this new feature, stress test it and help find new meaningful heuristics for GC. By default, the flag to allow `mempurge` is set to `false`.
