feat: Support for dropping extra callback args

[jnumainville]

Fixes #260

This snippet now works:

import deephaven.ui as ui
from deephaven.ui import use_state


@ui.component
def counter():
    count, set_count = use_state(0)
    return [
      # Pass in a function that accepts the event argument
      ui.action_button(f"Foo {count}", on_press=lambda e: set_count(count + 1)),
      # Pass in a function that does not have any positional arguments
      ui.action_button(f"Bar {count}", on_press=lambda: set_count(count + 1))
    ]


c = counter()

This implementation is more robust than that though. It supports:

1. Dropping any number of positional args. For example, if the callback supports 3 positional args but only two are defined, the third will be not be passed in.
2. Dropping any unused keyword args.
3. If *args or **kwargs are used, all of the relevant args are passed in.

Sweet. As a side note, the kwargs was unnecessary - JS will only be allowed to call positional arguments anyways. But it does make the solution more general/complete so I like that.
