Changeset 29916 for trunk/tests/phpunit/tests/multisite/bootstrap.php

Split and organize multisite unit tests

• Move ms.php to multisite.php
• Create multisite.php under directories option/ and user/ to better match existing structure.
• Create a multisite/ directory containing bootstrap.php, site.php, and network.php for very multisite specific testing.
• Add unit test groups ms-site, ms-user, ms-option, ms-network, and ms-bootstrap.

Fixes #29896
