Add a limits and trap-on-OOM options to the CLI (#6149)

* Add a limits and trap-on-OOM options to the CLI

This commit adds new options to the `wasmtime` CLI to control the
`Store::limiter` behavior at runtime. This enables artificially
restriction the memory usage of the wasm instance, for example.
Additionally a new option is added to `StoreLimits` to force a trap on
growth failure. This is intended to help quickly debug modules with
backtraces if OOM is happening, or even diagnosing if OOM is happening
in the first place.

* Fix compile of fuzzing oracle
