Jon Coppeard 95257109ee Bug 1761938 - Part 4: Give module loaders a global object field r=smaug,yulia
This gives the module loader a field for the current global, since a module map
is only associated with a single global.

This adds a method to Document to tell the script loader when its global
changes. I'm not sure of when we do this exactly.
