Message:

Tests/Build Tools: Improve tests for bundled themes.

Introduce two new tests relating to bundled themes:

1. Ensure the list of tested themes matches the list of themes defined in WP_Theme
2. Ensure the run time value of WP_DEFAULT_THEME is included in the list of themes defined in WP_Theme

See #61530.
