@mantine/notifications Allow global notifications auto close customization

[dillonstreator]

This PR proposes extending the autoClose functionality by allowing a callback to be specified (in addition to the existing number | false) that receives the NotificationData and returns number | false. This enables creating a "global" default ruleset/config on the Notifications component.

import { Notifications, NotificationData, DEFAULT_AUTO_CLOSE_DURATION_MS } from '@mantine/notifications';

// red notifications will require manual close while all others close in the default auto close duration (4000ms)
function Demo() {
  return <Notifications autoClose={(data: NotificationData) => {
    if (data.color === 'red') return false;

    return DEFAULT_AUTO_CLOSE_DURATION_MS;
  }} />;
}

This global config can be overridden at the time of calling showNotification by specifying autoClose.
