Show "named blocks"

[lifeart]

it will be great to have ability to see "named blocks" usage in component explorer

why?

in ember v3.25.0-beta.1 named blocks enabled

emberjs/ember.js#19318

@lifeart how exactly would you like this feature to work?

[lifeart]

@rwwagner90 I think it may be <:slotName><InternalComponentIfExists /></:slotName> in component explorer, if there is no components inside slot (but thers is some dom nodes), it may be <:slotName /> .

[RobbieTheWagner]

@lifeart would the slots be selectable? If so, what data would we show?

[lifeart]

Yes, I think slots should be selectable, and we could show slot's position arguments

{{yield (hash a=1) "foo" "bar" to="heder"}}

[ {a: 1}, "foo", "bar" ]

[chancancode]

I would like to see this, but right now we don't really have the information to do it from the debug render tree. So the first step would be to make that work, and then we can work out the display format here

@chancancode follow-up request - have ability to see "if"s and "each" blocks (areas)
