fix(VMenu): avoid aria-owns for menu activators

[vianmangal]

Description

Fixes #22540.

VMenu activators now use aria-controls without also exposing aria-owns, which prevents Safari VoiceOver from dropping the accessible labels of menu items. Nested-overlay ownership tracking still works through a private data-v-overlay-activator attribute, preserving focus restoration for nested menus.

A browser regression test verifies that menu activators retain aria-controls and no longer receive aria-owns.

Validation:

• pnpm --filter vuetify test:browser src/components/VMenu/__tests__/VMenu.spec.browser.tsx --run — 17 passed
• Targeted ESLint for the three changed files — passed
• pnpm --filter vuetify exec tsgo -p tsconfig.checks.json --noEmit --pretty — passed

Markup:

<template>
  <v-app>
    <v-container>
      <v-menu>
        <template #activator="{ props }">
          <v-btn v-bind="props">Open menu</v-btn>
        </template>

        <v-list>
          <v-list-item title="Click me" />
        </v-list>
      </v-menu>
    </v-container>
  </v-app>
</template>
