fix(view)!: properly handle scoped view-components

[brendt]

TODO:

• Refactor dynamic view component to be file-based
• Remove ViewComponent interface and refactor AnonymousViewComponent
• Update meta:view-component command
• Make updates to the docs: Update view component docs and specs #1436
• Always pass view data into view components

The breaking change is about view components not having access to outer scopes anymore (except for variables from the view itself):

<!-- x-base.view.php -->

{{ $title }}

<!-- Let's say `$title` was defined in the current view -->

<?php $title = 'Hello'; ?>

<!-- this won't work anymore: -->
<x-base />

<!-- you would need to explicitly pass in `$title`: -->
<x-base :title="$title" />

The other breaking change is the use statements within view files must now always go on top.

Originally, this PR was only meant to address #1425 , but in order to make it work, I'd have to refactor view-component scopes. That's why they are both combined. The scope change is the only thing people will notice, so I decided to name this PR accordingly.

Closes #1425
