fix(NcTextField): don't fire value updating events twice

[ShGKme]

☑️ Resolves

• Events are fired twice:
  • Once in @input="handleInput" which results in $emit('update:value', $event.target.value)
  • Once in v-on="$listeners" which equivalent to @update:value="$emit('update:value', $event)"
• Before v-model compatibility it was only for update:value event. Now also for all the modelValue events

Handling input manually is not needed, it's handled by NcInputField

Vue 3 works differently, making a separate PR for v9.
