[Feature request] Form item warnings and errors

[rejifald]

I suggest to add special props to va-form-item, or slots, or even both, where can be placed errors and warnings.
WDYT ?

this would be for you to define a location for the errors generated by the child component's validation, overriding the default location?

or am I misunderstanding?

I think it's just for case when i will want to put there icon...
But maybe it's not important, because we can use built-in style.
But what is actually great thing, in my opinion, is built-in validation behavior.

1. Call validation before submit
2. Call validation when input lost focus at the first time
   It will be very convenient.
