Support for promise_batch_action_function_call_weight

Assumed this would be used by the SDK, but this simplifies the devX a lot because it doesn't require someone to specify gas explicitly. I have noticed developers having issues with this getting started.

There isn't really a clear path to migrate the APIs without being breaking. Basically what needs to happen is gas being made optional and also including the optional parameter of gasWeight. Possibly a non-breaking change would be to make gas optional and just add gasWeight as the next positional argument, which is not ideal because it requires specifying a gas value if you only want to modify the weight, and these can be confused.

The builder would have to be modified to include (or change) the existing near_promise_batch_action_function_call to call the updated runtime host function.

Great demostration on promise_batch_action_function_call_weight. We also need to figure out integration of protocol version in build cli, to include recent and future APIs.
