Fix crash when enumerating properties of global object (#36491)

These changes make our implementation of the enumeration hook for
globals [match
Gecko's](https://searchfox.org/mozilla-central/rev/1f65969e57c757146e3e548614b49d3a4168eeb8/dom/base/nsGlobalWindowInner.cpp#3297),
fixing an assertion failure that occurred in the previous
implementation.

Our enumeration hook is supposed to fill a vector with names of
properties on the global object without modifying the global in any way;
instead we were defining all of the missing webidl interfaces. We now do
much less work and crash less.

Testing: New crashtest based on manual testcase.
Fixes: #34686
