fix(VTextField): forward title attribute to root element

[hellozzm]

Summary

The title HTML attribute was being routed to the <input> element via inputAttrs in filterInputAttrs. For VSelect, the actual <input> is hidden, so the title tooltip never appears on hover.

This fix adds title to the rootAttrs pick list in filterInputAttrs, so it gets applied to the root element where it can function as a native browser tooltip.

Playground Markup

<template>
  <v-app>
    <v-container style="max-width: 400px">
      <v-select
        label="Select a fruit"
        title="Hover over me to see this tooltip"
        :items="["Apple", "Banana", "Cherry"]"
      ></v-select>
      
      <v-text-field
        label="Text field"
        title="This also has a title tooltip"
        model-value="Hello"
      ></v-text-field>
    </v-container>
  </v-app>
</template>

<script setup>
</script>

Testing

1. Open the playground above
2. Hover over the VSelect component (not the dropdown, the closed state)
3. A native browser tooltip should appear saying "Hover over me to see this tooltip"
4. Hover over the VTextField - tooltip should also appear
5. Before fix: no tooltip appeared on VSelect
