feat(js/tracing): invoke js's step inside step_end

[jsvisa]

fix #200 with the following adjusts:

1. invoke step_fn from step into step_end;
2. copy stake and memory at the ending of step;

waiting for #222 and bluealloy/revm#1820 to be merged first.

but failed with below issues: stake/memory related JS functions maybe failed.

Because we're invoking step_fn.call in step_end, seems the stack and memory are messed up, so if we try to call those functions inside JS's step(eg: log.stack.peek(0)) the JS binding will be failed, maybe it's caused by the JsInspector::Context, but as boe_engine::Context doesn't implemated Copy, we can't store the step's Context as the environment to used in the step_end
