#19879: Better caching for get_dirsize

--------------------------+-----------------------------
 In a multisite install, when trying to determine whether a site has
 exceeded its storage quota, WordPress will scan through a blog's upload
 directory and sum up the file sizes, by running {{{filesize}}} against
 each one. With a large number of files, this can significantly slow down
 the upload process or certain portions of the Dashboard.

 {{{get_dirsize}}} has transient caching in place but this is a single
 cache entry for all folders. It might be better if WordPress has a
 separate cache entry for each folder and was invalidated based on context
 so that get_dirsize does not need to be run constantly on older, unchanged
 directories as frequently.
