This allows us to treat tasks from different layers id as independent,
thereby removing the unnecessary latency increase as described in bug
1449982 comment 33.
Note that we could probably implement this by actually maintaining
separate queues for each layers id, but that involves more overhead
since we would need to have a map from layers id to task queue, and
removing entries from that map becomes tricky with respect to locking
and timing.

This makes it so that we only process a UpdateHitTestingTree task (and any
tasks queued after it) once we know that the corresponding scene has
been built and swapped in by WebRender. This ensures that processing of
APZ data stays in sync with the active scene in WR.
The way we do this is by tracking the "epoch" (which is updated per
WR/layers transaction) that the APZ messages are based on. Only once the
scene for that transaction is swapped in do we process those messages.

This allows us to easily store a handle to the APZUpdater on the
WebRenderScrollDataWrapper class and walk around in the scroll data tree
without having to query other classes like CompositorBridgeParent or
WebRenderBridgeParent when we encounter a reflayer boundary.

I don't know why we keep using plain uint32_t and uint64_t values when
we have better types that we can use. This makes the code use and store
wr::Epoch natively instead of raw uint32_t values that are wrapped
on-demand.

If we're using the WR scene builder thread as the updater thread, we
cannot just post a task to its message loop, because it's a rust thread
that doesn't have a message loop. Instead, we put these tasks into a queue
that we will process in callbacks that are invoked from the updater
thread.
This patch just adds the basic queue machinery, it will get more
complicated in a future patch because we need to gate the tasks to make
sure they don't run too early.

This lets the APZUpdater know which thread is the actual updater thread.
This is only really used for the thread assertions, but might be useful
for debugging and such as well.

This is all the (bidirectional) glue that connects the SceneBuilderHooks
to the APZUpdater.

Until all the pieces are in place, turning on this pref will probably
break horribly. But we need the pref so we can add the rest of the
pieces without enabling them by default.

This will allow callbacks from rust code to get a handle to the
necessary APZUpdater instance on which to invoke functions.

This includes a signature change from CompositorBridgeParentBase ->
CompositorBridgeParent which is not strictly required, but it makes it less
likely that we'll accidentally create a WebRenderAPI from somewhere else
and pass a nonsense window id. In effect, the signature change makes it
likely that only CompositorBridgeParent will allocate the window ids.

If we have a non-null mTarget, we already set mDrawTarget to mTarget. So "mTarget ? mTarget : mDrawTarget" will always evaluate to mDrawTarget.

The same condition is checked just before this if, so it's always true.

This was incorrectly using the invalid rect, so it was clearing more than
necessary and not taking advantage of the opaque region that the caller computes.
The idea is that we don't need to clear parts of the invalid region that will be
covered by something opaque.

It's not needed, because by default std::unorderd_map will use
std::equal_to which delegates to the operator== on LayersId which does
the same thing. We don't need to reimplement it.
