Cache API: Handle numerically-keyed global_groups when switching sites.

This commit protects against another multisite cache edge-case where a persistent object-cache drop-in plugin (namely memcached) may use a numerically-keyed `global_groups` array instead of `'key' => true` like the default object-cache class, and includes the following changes:

* Use `wp_is_numeric_array()` inside of `wp_cache_switch_to_blog_fallback()` so that the global group names array are always properly formatted regardless of the caching back-end in use
* Add private helper methods to `Tests_Multisite_WpCacheSwitchToBlogFallback` to properly format global group names, and tweak a few tests to make them more resilient to different caching back-ends

Follow up to r61760.

See #23290.
