DOM's initEvent says that it must do nothing during dispatch. UI Events
says they behave the same as initEvent, so the legacy initializers
defined there also shouldn't do anything during dispatch. Previously we
only did this for initEvent itself, but other legacy initializers would
function normally during dispatch.
Edge passes the wpt test that's updated in this commit. Chrome passes
all but initCustomEvent. It would be nice to expand the test to have
coverage for all our legacy initializers, but the likelihood of
real-world compat issues from this behavior is slim enough that I didn't
think it was worth the effort.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

This patch was generated with the following command:
find . -name "*.h" -o -name "*.cpp" | xargs perl -pi -e 's/return ([a-zA-Z0-9]+)\.ErrorCode\(\);/return \1.StealNSResult();/'
This patch was mostly generated with the following command:
find . -name "*.h" -o -name "*.cpp" | xargs sed -e '/WrapObject(JSContext/ {; N; s/\(WrapObject(JSContext *\* *a\{0,1\}[Cc]x\),\n\{0,1\} *JS::Handle<JSObject\*> a\{0,1\}[sS]cope/\1/ ; }' -i ""
and then reverting the changes that made to
dom/bindings/BindingUtils.h, since those WrapObject methods are not
the ones we're trying to change here, plus a bunch of manual fixups
for cases that this command did not catch (including all the callsites
of WrapObject()).
This patch was mostly generated with this command:

plus a few manual fixes to dom/bindings/Codegen.py, js/xpconnect/src/event_impl_gen.py, and a few C++ files that were not caught in the search-and-replace above.
