[5.4] Add @dump() blade directive

[calebporzio]

I have a personal custom blade directive called @Dump()

I think it would be handy in the core. Similar to $browser->dump() and things like that.

I originally called it @dd, but decided to go with @Dump - I'm personally fine with either.

If it's @dump why it's calling dd()? :}

[browner12]

isn't it just as quick to write {{ dd($var) }}?

[decadence]

Better to use dump than dd. And it was rejected already before.

[decadence]

And directive is called dump but calls dd behind the scenes. A little inconsistent.

[calebporzio]

aaah k, couldn't find any previous PRs for this at first glance.

I don't like {{ dd() }} because I would never write echo dd() -> it feels off to me.

I'm not sure I can verbalize why I went with @Dump - but it reads better to me. Like: dd() is the helper function we all know about and "dump" is when you want to achieve a similar effect in a different context.

You can just echo it 😄
