feat(ui): confirmation modal (#11271)

There are nearly a dozen independent implementations of the same modal
spread throughout the admin panel and various plugins. These modals are
used to confirm or cancel an action, such as deleting a document, bulk
publishing, etc. Each of these instances is nearly identical, leading to
unnecessary development efforts when creating them, inconsistent UI, and
duplicative stylesheets.

Everything is now standardized behind a new `ConfirmationModal`
component. This modal comes with a standard API that is flexible enough
to replace nearly every instance. This component has also been exported
for reuse.

Here is a basic example of how to use it:

```tsx
'use client'
import { ConfirmationModal, useModal } from '@payloadcms/ui'
import React, { Fragment } from 'react'

const modalSlug = 'my-confirmation-modal'

export function MyComponent() {
  const { openModal } = useModal()

  return (
    <Fragment>
      <button
        onClick={() => {
          openModal(modalSlug)
        }}
        type="button"
      >
        Do something
      </button>
      <ConfirmationModal
        heading="Are you sure?"
        body="Confirm or cancel before proceeding."
        modalSlug={modalSlug}
        onConfirm={({ closeConfirmationModal, setConfirming }) => {
          // do something
          setConfirming(false)
          closeConfirmationModal()
        }}
      />
    </Fragment>
  )
}
```
