Currently, for auto scroller, when a `mousedown` happens, a possible run order is that
`mousedown(parent process)` -> `scroll stopped (parent process)` ->
`mousedown(child process)`, so that the last mousedown(child process)
would start the scrolling again.
This patch adds a new check to the last `mousedown(child process)`
handler, to not starting the scrolling again if preventClickEvent has
been called on this event.

Chrome behaves like this:
1. When user starts autoscroll with a middle click, `mousedown` and `mouseup`
are fired, but `auxclick` nor `paste` event is not fired.
2. When user ends autoscroll with a left click, only `mouseup` event is fired.
I.e, `mousedown` nor `click` event is not fired.
3. When user ends autoscroll with a middle click, only `mouseup` event is fired.
I.e., `mousedown`, `auxclick` nor `paste` events is not fired.
4. When user ends autoscroll with a right click, `mouseup` and `contextmenu`
events are fired, but `mousedown` and `auxclick` events are not fired.
This patch emulates these Chrome's behavior as far as possible. However,
unfortunately, we cannot do exactly same behavior without some big patches
because each widget (`nsWindow` or `nsChildView`) discards a mouse event
which rolled up a widget before dispatching it into the DOM. Therefore,
for now, this patch does not fix the following issues:
1. `mousedown` event is not fired in content when clicking outside the
autoscroller to close it except when pressing the secondary button or on any
buttons on Linux.
2. `mouseup` event is not fired in content when clicking outside the
autoscroller to close it except when pressing the primary button macOS.
3. `click` event and `auxclick` events are fired when clicking outside the
autoscroller with the secondary button.
So, the middle button `click`/`auxclick` events and `paste` event which is
reported to the bug won't be fired with this patch. I'll file follow up bugs.

Moved mozilla::WidgetMosueEventBase::buttonType in MouseEvents.h to mozilla::MouseButton in EventForwards.h, and mozilla::WidgetMouseEventBase::buttonsFlag to mozilla::MouseButtonsFlag so that any referer in header files do not need to include MouseEvents.h only for referring them. Instead, they just need to include EventForwards.h. Now when MouseEvents.h is changed, the rebuild speed becomes faster.

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.

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.
