I think at this point we can remove all of RemoteWebProgressManager, some/all of the TabProgressListener recreations, and probably a bunch more.

The 'asyncStack' flag on JS execution contexts is used as a general switch
to enable async stack capture across all locations in SpiderMonkey, but
this causes problems because it can at times be too much of a performance
burden to general and track all of these stacks.
Since the introduction of this option, we have only enabled it on Nightly
and DevEdition for non-mobile builds, which has left a lot of users unable
to take advantage of this data while debugging.
This patch enables async stack traces across all of Firefox, but introduces
a new pref to toggle the scope of the actual expensive part of async stacks,
which is _capturing_ them and keeping them alive in memory. The new pref
limits the capturing of async stack traces to only debuggees, unless an
explicit pref is flipped to capture async traces for all cases.
This means that while async stacks are technically enabled, and code could
manually capture a stack and pass it back to SpiderMonkey and see that stack
reflected in later captured stacks, SpiderMonkey itself and related async
DOM APIs, among others, will not capture stacks or pass them to SpiderMonkey,
so there should be no general change in performance by enabling the broader
feature itself, unless the user is actively debugging the page.
One effect of this patch is that if you have the debugger open and then close
it, objects that have async stacks associated with them will retain those
stacks and they will continue to show up in stack traces, no _new_ stacks
will be captured. jorendorff and I have decided that this is okay because
the expectation that the debugger fully revert every possible effect that it
could have on a page is a nice goal but not a strict requirement.

These tests used <iframe mozbrowser> for convenience, mostly forcing
themselves to only run in non-e10s mode in the process, but none of them
really have any need to.

Previously, the PWindowGlobal actor was managed by the PBrowser which hosted it,
however this could cause issues when the tab containing the PWindowGlobal was
being destroyed. Due to the slightly different lifecycles of the PBrowser actor
and the nsGlobalWindowInner which the PWindowGlobal was trying to match the
lifetime of, the actor would sometimes not fire 'willDestroy' events correctly.
This patch moves PWindowGlobal to be directly managed by PContent, and changes
logic which previously used `Manager()` to get `Browser{Parent,Child}` to
instead use a pointer member.

After bug 1582832, DocShell destruction and BrowsingContext detaching happen
in separate operations, leaving a gap where a DocShell has been destroyed, but
its BrowsingContext is still considered attached. During this gap, the usual
invariant that an in-process, attached BrowsingContext always has an
associated DOM window doesn't hold, nor do the usual invariants for outer
window forwarding security checks.
This patch fixes the detach timing so that a child BrowsingContext for a frame
which has been removed is always marked detached at the same time its DocShell
is destroyed.
