Import Twenty Twenty-Five

[poena]

Add the new default theme to core in time for Beta 1.

Twenty Twenty-Five is being developed on this GitHub repository: ​https://github.com/WordPress/twentytwentyfive

@desrosj I will probably need help with:

• the binary files
• how to get the list of props from the GitHub props bot
• GitHub actions

Because of the time of the beta release, the theme needs to be added on Monday the 30th at the latest.

The theme has a large number of text strings in PHP files that are not inside translation functions.
This is known and will be handled before the string freeze. For other known issues please see ​https://github.com/WordPress/twentytwentyfive/issues

Thank you!

I think src/wp-admin/includes/update-core.php should also have $_new_bundled_files updated

In 59151:

Bundled Themes: Second follow up import of Twenty Twenty-Five.

Remove TT5 from performance tests as the baseline tests run against an older version of WordPress that do not include all of the functions used in the new theme.

Follow up to [59146], [59150].

Props mukesh27.
See #62103.

In 59227:

Bundled Themes: Test new themes are added to new bundled files.

Introduces a test to ensure that new bundled themes are included in the $_new_bundled_files array. Modifies previous theme related tests added during the 6.7 release cycle to include the correct annotations.
