This PR contains just the breaking changes required for the upcoming store implementation. It adds two new primitives:
Mutable mapped signals (without a different subscriber list). This lets you scope a writable value and pass it to a child component. It requires two closures to map the immutable and mutable references to the inner signal. With stores, these closures will be derived
Boxed readable and writable values (ReadSignal, and WriteSignal). Any readable or writable types can be converted to a read signal or write signal with the boxed method or built in types are automatically converted into the boxed variants when passing into props
* map signals mutably
