feat(VColorPicker): add hide-eye-dropper prop

[yimme]

Description

resolves #19150

Why is this change required?

You currently can't disable the eye-dropper in v-color-picker if its enabled on your browser.
When you do want it hidden you have to write some custom css to force hide it.

What problem does it solve?

The lack of hiding it using a prop on the component itself.

Markup:

<template>
  <v-app>
    <v-container>
      <v-color-picker hide-eye-dropper />
    </v-container>
  </v-app>
</template>

<script setup>
</script>

Yes please. The eye dropper seems very buggy, and in my experience adds unexpected levels of alpha, even when the color-picker is in RGB mode.
