[TwigComponent] support passing data to `component()` variadically

[kbond]

This would remove an array level from the component function:

{{ component('my_component', { prop1: 1, prop2: 2 }) }}

{# could be shortened to: #}

{{ component('my_component', prop1: 1, prop2: 2) }}

Can this be done in a BC way?

I discovered this currently can't work as twig snake-cases variadic properties. For {{ component('my_component', prop1: 1, prop2: 2) }}, prop1 and prop2 are received as prop_1 and prop_2.

Thank you for this issue. There has not been a lot of activity here for a while. Has this been resolved?
