f46fbae857
Adds the `wp_set_script_translations()` function which registers translations for a JavaScript file. This function takes a handle, domain and optionally a path and ensures JavaScript translation files are loaded if they exist. Merges [43825,43828,43859,43898] from the 5.0 branch to trunk. Props herregroen, atimmer, omarreiss, nerrad, swissspidy, ocean90, georgestephanis. Fixes #45103, #45256. Built from https://develop.svn.wordpress.org/trunk@44169 git-svn-id: http://core.svn.wordpress.org/trunk@43999 1a063a9b-81f0-0310-95a4-ce76da25c4cd
