fix(VSelect): pass title attribute to root element

[sridhar-3009]

Summary

Fixes #22730

The HTML title attribute was not being forwarded to the root element on v-select (and other input-based components), so tooltip-on-hover via <v-select title="foo"> had no effect.

Root cause: filterInputAttrs in src/util/helpers.ts splits fallthrough attributes into two groups:

• rootAttrs → applied to the component's root element (class, style, id, inert, data-*, event listeners)
• inputAttrs → applied to the inner <input> element

title was not in the root list, so it landed on the inner <input> which is hidden/inert in v-select and not visible to the user.

Fix: Add 'title' to the list of attributes forwarded to the root element in filterInputAttrs.

This single-line change fixes title for all components that use filterInputAttrs:

• v-select
• v-text-field
• v-textarea
• v-slider / v-range-slider
• v-otp-input
• v-selection-control (checkbox, radio, switch)
• v-file-upload
• v-radio-group
• v-img

Test plan

• Add title="foo" to a v-select and verify the browser tooltip appears on hover over the control
• Verify the same works on v-text-field, v-textarea, v-slider
• Existing tests pass: pnpm test

Demo

Behavior change might feel like regression

• VTextField append slots started showing title and require their own title='...' in case field title is not appropriate
• Most of the other components started showing title when hovering hint/error/counter and labels

If you the PR states fix(VSelect), it would be nice to avoid affecting everything else.
