This exposes the layers id on the APZ hit result testing API, and
updates callers to check the layers id is correct. This is mostly
unnecessary for these tests, but introduces machinery that will be
useful in Fission-enabled tests, where iframes may be OOP and have
different layers ids.

This patch extracts two additional CompositorHitTestInfo flags from the
eDispatchToContent flag; eApzAwareListeners for elements that have
APZ-aware listeners, and eInactiveScrollframe for inactive scrollframe
or unlayerized scrollthumbs. The eDispatchToContent is then renamed to
eIrregularArea to reflect the fact that it is used for irregular-shaped
areas that require main-thread hit-testing.
Additionally, it is important to note that when using the non-WebRender
codepath, all three of these flags still end up gettings squashed into
the "dispatch to content" region on the EventRegions; when APZ
reconstructs a CompositorHitTestInfo it will turn anything in this
region back into an eIrregularArea. So this is a lossy round-trip
conversion for the non-WebRender case. However it should still result in
correct behaviour because the semantics of eIrregularArea result in APZ
relying on the main-thread to do hit-testing and so any APZ-aware
listeners and inactive scrollframes are also handled by the main-thread.

This allows us to fire MozMouseHittest events from tests and then read
the hittest result from the compositor APZTestData. The MozMouseHittest
event was chosen in particular because the existing uses of it are
similar in nature - it is a dummy event that is used to determine what
elements a particular coordinate targets. It is also an event that is
never generated by the OS and so using this event gives us more control
over what ends up in the APZTestData.
