Add medium_large size to the image_downsize filter

[anigeluk]

Description

We currently filter image_downsize using most of the default reserved image sizes but still need to include medium_large. This means that anyone using medium_large as an image size gets the wrong height and width returned.

Changelog Description

Fixed

• Fixed image_downsize filer to be aware of the reserved size medium_large

-Checkout the changed a8c-files.php and retest the image size and you should get the correct default width for medium_large of 768px
