Lock file maintenance (#40515)

* Lock file maintenance
* Address Phan issues due to php-stubs/wordpress-stubs upgrade
  * Some typecasts to account for better Core type delcarations.
  * Suppress `current_user_can_for_blog` → `current_user_can_for_site`
    until we drop 6.6 support.
* Hack around Core SimplePie renaming

  Core upgraded their copy-pasted SimplePie library, which included
  renaming all the classes. While they did provide back-compat aliases, we
  run into a few problems:

  * A method parameter type of `SimplePie_Item` won't accept
    `SimplePie\Item`, while `SimplePie\Item` won't work on WP 6.6.
  * It's really hard to make Phan happy for both the two runs (with 6.7
    stubs and with 6.6 stubs).

  The best I was able to come up with was this:
  * Turn on `enable_class_alias_support`.
  * Alias `Jetpack\SimplePie\<name>` to the appropriate classes, and use
    those aliases everywhere.
    * Have phan load only one of the two alias files, depending on which
  	run it's doing.
  * Merge all the test mocks into one file and load them from
    bootstrap.php.
