Pascal Birchler 47687d8799 Editor: Prevent font folder naive filtering causing infinite loops.
This modifies the font directory API to more closely reflect the upload directory API to help account for naive filtering when uploading fonts.

This moves the protection of infinite loops to the new function `_wp_filter_font_directory()` to allow developers extending and maintaining the font library to apply the filter without the need for a closure.

These changes also ensure both the `upload_dir` and `font_dir` filter are applied consistently when both creating and deleting fonts faces. Prior to this commit the `upload_dir` filter was only fired when creating fonts faces via the REST API.

Applying the font directory filter to the `upload_dir` filter is now done by adding the `_wp_filter_font_directory` function rather than `wp_get_font_dir()`. Developers who have previously modified the font upload directory using the `font_dir` filter will NOT need to upload their code.

Extenders wishing to upload files to the font directory can do so via the code:

{{{#!php
<?php
add_filter( 'upload_dir', '_wp_filter_font_directory' );
// Your code to upload or sideload a font file.
remove_filter( 'upload_dir', '_wp_filter_font_directory' );
}}}

Introduces:

* `wp_font_dir()`: Attempt to create and retrieve the font upload directory. The equivalent to `wp_upload_dir()`.
* `_wp_filter_font_directory()`: To run on the `upload_dir` filter, this sets the default destination of the fonts directory and fires the `font_dir` filter. 

`wp_get_font_dir()` has been modified to be a lightweight getter for the font directory. It returns the location without attempting to create it. The equivalent to `wp_get_upload_dir()`.
