Ability to support generics in ActionBuilder derived Component struct.

[BartoszF]

Hi, I am trying to use generic components to look for targets.

In plain bevy it works fine, but when I try to add it to big-brain, I got an error.

#[derive(Clone, Component, Debug, ActionBuilder)]
pub struct Find<T> (PhantomData<T>);

impl<T> Find<T> {
    fn new() -> Self {
        Find(PhantomData)
    }
}

Error:

37 | pub struct Find<T> (PhantomData<T>);
   |            ^^^^ expected 1 generic argument
   |
note: struct defined here, with 1 generic parameter: `T`

This probably just needs the derive macro to add support for generics.
