Description (last modified by mikeschroder)

This is a follow-up to #24498 and the research that @tollmanz did on the query used in meta_form. To summarize:

The query in meta_form can be incredibly slow on sites with a lot of post meta.

The solution to me seems to be to cache the query and update the cache of meta to use every time a new piece of post_meta is saved. This will prevent the query from needing to be run on sites with a persistent cache.
