[8.x] Autoload class components

[driesvints]

Use Blade::componentNamespace to register a package namespace with class based components to autoload them. This allows package maintainers to not manually register every component anymore.

For example, a package with a namespace of Package\Components has a class based component at src/Components/FooBar/Baz.php.

Register the component's namespace together with the package name:

Blade::componentNamespace('Package\\Components', 'package');

Usage:

<x-package::foo-bar.baz />

This takes precedence over loading anonymous components: #33954

Doesn't this break if two classes in different namespaces have the same name, where as before it worked fine, because the classes were qualified? EDIT: I think I read the code wrong. ;)
