Ability to wire a block without a physical component class

[wpoortman]

Sometimes you just want to transform a block into a Magewire component so it's able to just refresh itself based on a emit. It would be a cool little feature when you have the option to just wire it within the layout XML, without a physical class, and Magewire will automatically generate a virtual component class for it.

Can look like this:

<arguments>
    <argument name="magewire" xsi:type="boolean">true</argument>
</arguments>

This should be done in:

\Magewirephp\Magewire\Helper\Component

Where a check can be made if the magewire argument === true.

This is getting somewhere: 6d7d53b... one issue to solve and it should give developers the ability to bind a virtual component onto a block by just defining a magewire argument with a true value.

It now also enables to unbind magewire from a block by defining false!
