Subject: [PATCH] Remove the ability to pass in more than one font to the
 `_prepareFontLoadEvent` method (PR 10539 follow-up)

After the changes in PR 10539 (which landed over three years ago) the `FontLoader.bind` method can only be called with *a single* font at a time, hence the `_prepareFontLoadEvent` method obviously don't need to support multiple fonts any more.
