Feeds: Cache RSS feeds in global transients.

Browse Source 
Moves the caching of RSS feeds requested via `fetch_feed()` from single site transients (`get|set|delete_transient()`) to global transients (`get|set|delete_site_transient()`).

On multisite installs of WordPress, this replaces per site caching with the global multisite cache to allow a single cache to be shared between all sites. This reduces the amount of data stored in the database and improves performance of feeds when multiple sites are ingesting the same URL.

Props rollybueno, spacedmonkey, peterwilsoncc.
Fixes #63719.

Built from https://develop.svn.wordpress.org/trunk@60524
