fix(VAutocomplete): prevent menu icon from toggling twice

resolves #23197

Description

When open-on-focus and close-on-input-click were used together, clicking the menu icon while the field was unfocused caused the menu to toggle twice. The menu would briefly open and immediately close.

This change ensures that the menu icon toggles the menu only when the field is already focused. A regression test was added for both VAutocomplete and VCombobox.

Markup:

<v-combobox
label="Combobox"
:items="['foo', 'bar']"
close-on-input-click
open-on-focus
/>
</v-container>
  </v-app>
