[5.x] Add support to display statamic widgets on resource index page

[saqueib]

This PR adds support for statamic widgets to be displayed on top of resource index page similar to Nova. To add a widget you just need to add widgets on resource configuration.

'resources' => [
	\App\Models\Order::class => [
	    'name' => 'Orders',
	    
	    // define all widgets for order resource
		'widgets' => [
                [
                    'type' => 'earning',
                    'width' => 50
                ],
                [
                    'type' => 'collection',
                    'collection' => 'pages',
                    'width' => 50
                ],
            ],
        ],
    ],
],

Hey 👋

Thanks for your pull request! However, I don't feel comfortable introducing these changes in Runway since they'd differ from the functionality offered in Statamic Core. For this reason, I'm going to close this PR.

You're welcome to PR similar functionality into Statamic Core. Then, once it's merged, feel free to re-open this PR and I can re-consider.

okay @duncanmcclean, I have got it working using view composer for my project. I thought it will be good feature to have in runway.
