`Autocomplete` validation refactor

[David-Moreira]

          I was just taking a brief look at `Autocomplete` validation, correct me if I'm wrong @stsrki 

but from what I can tell, in Autocomplete you either have to set the Validator or AsyncValidator parameters with your validation.


https://blazorise.com/docs/extensions/autocomplete

I believe Data Annotations aren't currently supported by Autocomplete in that case. Again correct me If I'm wrong.

Also I'd argue that we should remove the internal Validator and Validator / AsyncValidator and just have the validation work as regular Blazorise Validation would work, by wrapping with the Validations / Validator outside the Autocomplete.

@stsrki Let's consider if this is a worthy refactor

I just ran into a need for this as well. It would be a worthy addition

Autocomplete having it's own Validation is causing me a lot of problems because I use Fluent Validation everywhere else in my app.

Its not possible to use dataannotation/fluent validations at all when heavily used autocomplete does not support it...

Hello. We are aware of the limitations with validation on Autocomplete. But due to the needed changes we are planning to do it in 2.0 release.
