Add ability to define layouts in plugins

[HYR]

Would love to have the ability to register layouts via a plugin instead of having to have inside of the site/layouts folder.

Any Plugin Index.php

'layouts'     => [
    'default' => __DIR__ . '/layouts/default.php',
    'blog' => __DIR__ . '/layouts/blog.php',
    …
],

I just played around with the plugin and wondered why the plugin does not just use templates/layouts as the default part for storing layouts. That way, layouts could be registered without the need of a whole new extension API.

Our goal is to merge the layouts plugin into the core at some point. Then we'll also be able to easily provide a plugin extension for this feature.

This is now possible with our snippets with slots in 3.9
