Improve testability and coverage of wp_ext2type().

Browse Source 
* Following pattern of `wp_get_mime_types()`, introduce `wp_get_ext_types()` function. New function returns a filtered list of file types with their extensions.
* Use this function in new tests for `wp_ext2type()`.

Props borgesbruno.
