This commit suggest using a lambda for the RegisterHandlerCleanup calls
in RegisterHandleCleanups.

The motivation is to reduce some duplication and to make it a little
easier to read as all of the calls pass in the same arguments, apart
from casting the uv handle.

How about using #define macro? I worry about the performance reduce of lambda

#define V(hook)                                                                \
  RegisterHandleCleanup(                                                       \
      reinterpret_cast<uv_handle_t*>(hook), close_and_finish, nullptr)

  V(timer_handle());
  V(immediate_check_handle());
  V(immediate_idle_handle());
  V(&idle_prepare_handle_);
  V(&idle_check_handle_);
  V(&task_queues_async_);
#undef V

LGTM and please, no macro :)

@himself65 This code is only run once per Environment, so performance is a non-concern, but generally lambdas will perform on par with macros, so they're almost always the better choice.
