Core: Fire iframe script in its context, add doc param in globalEval

1. Support passing custom document to jQuery.globalEval; the script will be
   invoked in the context of this document.
2. Fire external scripts appended to iframe contents in that iframe context;
   this was already supported & tested for inline scripts but not for external
   ones.

Fixes gh-4518
Closes gh-4601
