[8.x] Allow index.blade.php views for anonymous components

[calebporzio]

For a hypothetical "accordion" anonymous Blade component system (a component with sub-components), I would love to use the following syntax:

<x-accordion>
    <x-accordion.item>
        ...

This PR allows me to use index.blade.php as a default view for an anonymous component pointing to a folder.

Here would be the folder structure

• components/accordion
  • index.blade.php
  • item.blade.php

This expands on the convention of index.html/php/js inside folders.

Without this addition, I have to use redundant wrapper names like: <x-accordion.accordion>, <x-accordion.group>, or have a file called accordion.blade.php at the same level as the accordion folder holding the sub-component views.

As far as breaking changes, because this addition is only run immediately before an error is thrown about not being able to find a view for a component, I don't see it causing any odd behavior for existing projects. I could have missed something though of course.

Thanks for your time and attention!

I really like this approach and I’m really exited to use it in my projects.

This is gonna open the door for Laravel Components Market!

PSA: You may need to run php artisan view:clear for this to work 😃

@brentarcane it's a good idea to always do that when updating Laravel.
