Allow control of autocomplete on entire forms.

[kfriars]

As you can see in the MDN Web Docs autocomplete is available on form elements.

It is available on <input> elements that take a text or numeric value as input, <textarea> elements, <select> elements, and <form> elements.

While Filament already supports the ability to set autocomplete on many fields, it does not currently support it on the form itself.

I would propose something like the following:

public static function form(Form $form): Form
{
    return $form
        ->autocomplete(false),
        ->schema([
            Forms\Components\TextInput::make('name')
                ->required()
                ->maxLength(255)
            Forms\Components\TextInput::make('number')
                ->required()
                ->maxLength(255)
        ]);
}

It can be much more efficient to specify autocomplete false on an entire form in some cases, rather than needing to specify it on every field.

If it is agreed this is an improvement, I can submit a PR and get the review process started.

Thanks!
