This is a large patch which tries to switch many of the external consumers of
nsGlobalWindow to instead use the new Inner or Outer variants.

When the dom.w3c_touch_events.enabled pref is set to "2" (autodetect) on Win/Linux,
it checks to see if the hardware supports touch events, and only enables the
DOM touch APIs if so. However, even if the hardware supports touch events, we
might have e10s or APZ disabled for other reasons, and in those cases we don't
actually turn on touch support in the widget (nsBaseWidget::RegisterTouchWindow
will not be called). So in those cases the widget will never actually dispatch
touch events, and the DOM touch APIs shouldn't be exposed either. This patch
implements this by checking the APZ state when deciding whether or not to
expose the DOM touch APIs.

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.

- all.js now sets dom.w3c_touch_events.enabled to auto-detect on all
platforms except windows and mac
- auto-detect always returns true for android and b2g
- graphene and tests override the all.js pref with their own value

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.

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()).

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.
