It appears that the Element member may have been creating a reference
cycle passing through the new strong WindowGlobalParent::Manager()
reference.
This patch also removes an unused member from BrowserParent which
otherwise may have needed to be cycle-collected.

There are a few IPDL actors which are cycle-collected, including `PBrowser`,
`PContent`, and `PWindowGlobal`.
This patch adds support for these actors to traverse and unlink the new strong
Manager() reference added by IPDL, allowing cycles containing these actors to
be properly unlinked and avoiding leaks.

Previously there was dead code handling DeallocPvsyncParent which hasn't been
called since PVsync was made refcounted. The new logic handles the reference
within IPC, and delays some initialization to the proper constructor.

Mouse events can be generated from other mouse events, e.g. mouseout event, and
these events can originate from different widgets, such as the notification
panel. In such case, we need to adjust the coordinates when sending to content
process.

This should not be needed anymore. We no longer need to "ack" an epoch,
since there's no epoch.
Make the logic to trigger a paint and request composite a bit more
generic. That doesn't change behavior right now, because our visibility
state is tied to mRenderLayers, but without this change setting
renderLayers = true on a display: none iframe will trigger a useless
paint after bug 1847584.

This seems to work, and turns out I need to fix this before bug 1847584,
because the epoch handling breaks with those patches in the case
customize mode sets display: none on browser elements.
Instead of dealing with epochs, just always report the last "has layers"
state to BrowserParent. This is both simpler and more reliable (there
were a couple hacks in WebRenderBridgeParent to make sure we notified
even though a transaction failed).
AsyncTabSwitcher pretty much already deals with this correctly because
it already needs to deal with browsers that already have layers, we only
had to loosen some assertions for potentially previous messages which
are fine.

This involved moving ApplyCache from the .h into the .cpp because now that the class is no longer a template, forward declaration of DocAccessibleParent is not sufficient.

For handling (ignoring) "too late" composition commit request from content
process, we need to distinguish a request is for which composition. Therefore,
we need to number each composition originated in the parent process.
This patch makes `TextComposition` instance which is created at first
composition event for a composition consider a composition ID in the parent
process and set it to composition events which are dispatched into the DOM
tree in the parent or sent to a remote process.
And also this patch adds the composition ID param to the request method of
committing composition and reply methods to notify the parent process of ending
a composition event handling.
The last patch handle them in `ContentCacheInParent` to consider
whether a request/reply should be ignored or handled.

There are some crash reports crashed in TSF module which may be caused by
passing invalid selection range (e.g., out of bounds of text). However,
the cache is created in the child process and that causes the invalid cache
creation does not appear in the crash reports. Therefore, let's try to
crash as soon as possible if `ContentCache` has invalid data.
Note that this does not detect all of the invalid cases because it's hard to
(re-)understand the edge cases. Therefore, this tries to detect the cases
checked in `ContentCacheInParent::HandleQueryContentEvent` (*1) and some other
obvious odd cases.
