Use Zeitwerk for code loading

[Spone]

Feature request

I was thinking about how to prevent #1377 from happening again, and I'd like to suggest using Zeitwerk for loading the view_component code, instead of all these autoload and require.

See here for what it would look like: https://github.com/fxn/zeitwerk#synopsis

We took this path in view_component-form, so you can have a look at the following PR to see what it took: pantographe/view_component-form#107 (keep in mind that the library is much simpler than view_component).

What do you think?

@Spone I'm generally OK with this if you'd like to take it on ❤️

I was unable to make it work for now, if someone else wants to take this on, I'm unassigning myself.
