Aryeh Gregor af57d2df0f Bug 1251198 - Remove various obsolete events from document.createEvent r=smaug
Other browsers do not support any of these (IIRC), telemetry reports
essentially zero usage, and supporting them is contrary to the DOM spec.

Notes on specific events:

CommandEvent and SimpleGestureEvent: These are not supposed to be
web-exposed APIs, so I hid the interfaces from web content too
(necessary to avoid test_all_synthetic_events.html failures).

DataContainerEvent: This was a non-standard substitute for CustomEvent
that seemed to have only one user, so I removed it entirely and switched
the user (MozillaFileLogger.js) to CustomEvent.

ScrollAreaEvent: This is entirely non-standard, but we apparently expose
it deliberately to web content, so I didn't see any reason to remove it
from createEvent.

SimpleGestureEvent and XULCommandEvent: Can still be created from
createEvent(), but not by content.

TimeEvent: This is still in because it has no constructor, so there's no
other way to create it.  Ideally we'd update the SMIL spec to add a
constructor.  I did remove TimeEvents.
