Component tree: input component arguents serialization

[lifeart]

ARGS looks confusing for non exp devs & non-inspectable

can be tests in https://ember-twiddle.com/a1a1448823aad56dfdd4615b0e5bf0b8?openFiles=templates.components.mega-input%5C.hbs%2C

Also, _TextField looks like private component, and I think it should be filtered.

Additional checks: <Textarea /> component

I’m not 100% sure what to do about this. It doesn’t seem great to just hide this.

@chancancode perhaps we could show built in components differently somehow?
