fix(VSelect/VAutocomplete/VCombobox): respect click outside

[yuwu9145]

fixes #20003

Cause

Click outside isn't triggered due to blur is triggered by "mousedown" which is before click outside happens

Solution

When "mousedown outside", menu shouldn't be closed as it will be closed by "click outside" later. But it should be closed when blur is triggered by TAB or calling blur() from javascript

Markup:

<template>
  <v-app>
    <v-main>
      <v-menu :close-on-content-click="false">
        <template #activator="{ props }">
          <v-btn v-bind="props">Open</v-btn>
        </template>
        <v-sheet class="pa-4">
          <div>
            <v-select
              label="Select"
              :items="['California', 'Colorado', 'Florida', 'Georgia', 'Texas', 'Wyoming']"
            />
            <v-autocomplete
              id="test"
              label="Autocomplete"
              :items="['California', 'Colorado', 'Florida', 'Georgia', 'Texas', 'Wyoming']"
            />
            <v-combobox
              label="Autocomplete"
              :items="['California', 'Colorado', 'Florida', 'Georgia', 'Texas', 'Wyoming']"
            />
          </div>
        </v-sheet>
      </v-menu>
      
    </v-main>
  </v-app>
</template>

<script setup>
import { ref } from 'vue'

const msg = ref('Hello World!')
</script>

Your changes look good but I'm curious as to what @KaelWD thinks.
