The other linux shell (and all the other embedding) have support for getting the locales from the system and sending them over the flutter/localization channel. The glfw shell does not have that which is causing a crash on an assert now that Locale is no longer nullable in Platform. This adds a similar approach to what is going on over in the other linux shell.
