The behavior for non-trusted events matches Safari (Chrome does return
deltaX in that case, which seems pretty bogus, because the sign of the
wheelDelta* is the opposite as the delta* props).

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.

There are three cases,
- Move to inner OOP frame.
- Move to outer OOP frame.
- Move to an OOP frame that is in different sub-tree.
We could use common BrowserParent ancestor to determine which case is and
dispatch MouseExitFromWidget event with proper ExitFrom type.
Depends on D84748

eTopLevel is reused in content process to indicates that the mouse leaves
the puppet widget rendering area, now we add a separated type, ePuppet, for it.

To correctly implement this, it must be known on instantiation whether E is
copy-constructible, which is not the case if only a forward declaration is
available. This can be resolved either by making sure a full definition of E is
available, which is preferable. But in cases where this is not (easily) possible,
the information can be explicitly provided by the MOZ_DECLARE_COPY_CONSTRUCTIBLE
and MOZ_DECLARE_NON_COPY_CONSTRUCTIBLE macros. In particular, declarations for
IPDL-declared types are added to nsTArray.h itself, like it was already done
for MOZ_DECLARE_RELOCATE_USING_MOVE_CONSTRUCTOR.

`synthesizePlainDragAndDrop()` synthesizes drag events with `DataTransfer`
object which is set to `DragEvent.dataTransfer` of `dragstart` after starting
drag session explicitly. However, this causes
`EventStateManager::DoDefaltDragStart()` does not initialize `nsIDragService`
instance. Therefore, synthesized drag events cannot work with editor because
`DragEvent::GetMozSourceNode()` returns `nullptr` due to
`nsIDragSession::GetSourceNode()` returning `nullptr`.
On the other hand, synthesized drag events cannot use
`nsIDragService::InvodeDragSession()` normally because of hitting an assertion.
https://searchfox.org/mozilla-central/rev/690e903ef689a4eca335b96bd903580394864a1c/widget/nsBaseDragService.cpp#230-233
This patch does:
- mark drag events caused by synthesized mouse events as "synthesized for tests"
- make `synthesizePlainDragAndDrop()` stop using
`nsIDragService.startDragSession()`
- make `nsBaseDragService` initialize and start session even for synthesized
`dragstart` event
- make `synthesizePlainDragAndDrop()` stop synthesizing drag events with
`DataTransfer` object since it's normal behavior and it'll be initialized
with `nsIDragService::GetDataTransfer()`
- make `nsBaseDragService` store `effectAllowed` for the session only when
it's synthesized session because it's required at initializing synthesized
default `dropEffect` value of `dragenter`, `dragover`, `dragexit` and `drop`
events' `dataTransfer`
- make all tests which use `nsIDragService.startDragSession()` use new
API, `nsIDragService.startDragSessionForTests()` to initialize session's
`effectAllowed` value
- make `EventStateManager::PostHandleEvent()` set drag end point of the test
session to `eDrop` event's screen point
- make `synthesizePlainDragAndDrop()` set drag end point of the session if
it does not synthesize `drop` event because following `endDragSession()`
use it at dispatching `dragend` event on the source element
Additionally, this adds `dumpFunc` new param to `synthesizePlainDragAndDrop()`
because it's really useful to investigate the reason why requesting DnD isn't
performed as expected.

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.
