This commit:
- removes sendRpcMessage, which was unused;
- removes the CPOW argument to sendAsyncMessage, broadcastAsyncMessage, and
sendSyncMessage;
- removes the aIsSync argument used internally to distinguish sendRpcMessage
and sendSyncMessage;
- removes CPOW tests;
- updates the few remaining callsites that use more than 2 arguments in
sendAsyncMessage for the removal of the cpows argument.

Before 1496578, URIFixup::keywordToURI used to do a synchronous IPC call to be
able to access search engines from the content process. Consumers of URIFixup
didn't care. Bug 1496578 moved the IPC messaging to the callers, in particular
nsDocShell, but assumed nsDocShellLoadState wasn't loading from content.
It looks like in some cases it does, so this adds another sync IPC call for
GetFixupURIInfo.
The total numer of sync IPCs should not change from before Bug 1496578, URIFIxup
was just doing it internally, while now it happens at the call point.
Note the long term plan would be for these docshell objects callers to just
handle URIs, while the UI code should do fixup.
Bug 1375244 tracks the removal of these sync IPC messages.

Crash annotations in content processes are currently sent over IPC via
shared memory buffers. To pave the way for the Rust rewrite of the exception
handler we are removing this code and gathering all the crash annotations
within the content processes themselves. This patch causes annotations to be
stored in the global table of each content process. They are then streamed
out to the parent process by the exception handler together with the
exception-time annotations.
This has a number of benefits:
* we have one less channel to exchange data between content processes and
the parent process
* we save memory because we don't need to allocate the shared memory buffers
* annotations are faster because we don't stream them all out every time one
changes
* we won't truncate annotations anymore if we run out of space in the shared
segment.
* we don't need delayed annotations anymore, so we can get rid of the
associated machinery
As I refactored the code I tried to adjust all the obsolete comments,
consolidate shared code and remove the redundant steps that were sometimes
present. In many places we had two entire crash annotation tables we merged to
change just a couple; that comes from the fact that historically we loaded
them from disk. Now it doesn't matter anymore and we can just go ahead and
change the ones we care about.

TabGroup never really made any difference in which thread something go
dispatched to. This was the intended use, but development of TabGroups
with abstract main threads never made it that far. The good thing is
that thish makes it safe to also remove to the SystemGroup and instead
switch all SystemGroup dispatches to dispatches to main thread.
Timers for setTimeout and workers were the sole users of wrapped and
throttled event targets, that those throttled queues have been moved
to the BrowsingContextGroup and are now accessed explicitly.
The SchedulerEventTarget has been removed, since there are no longer a
separate event target for every TaskCategory. Instead a
LabellingEventTarget has been added to DocGroup to handle the case
where an event is dispatched do DocGroup or when an AbstractThread is
created using a DocGroup. This means that we'll actually label more
events correctly with the DocGroup that they belong to.
DocGroups have also been moved to BrowsingContextGroup.

When marshaling a11y calls from the content process, there are quite a lot of cross-thread QueryInterface calls (ipc::mscom::Interceptor::QueryInterfaceTarget).
Some of these are for special COM interfaces like IAgileObject and IFastRundown, which we could just special case in Interceptor::QueryInterface like we do for INoMarshal.
However, it seems there are a lot of other interfaces being queried and it's not clear why.
This patch adds a new HandlerProvider method: IsInterfaceMaybeSupported.
This allows implementations to indicate when there are interfaces which they definitely don't support, allowing the call to be answered without a cross-thread call.

This patch extends shared memory freezing to support the use case where
the parent process retains write access for incremental updates, while
other processes receive read-only access.
Note that, while some OSes allow independent read-only and read/write
capabilities for the same object, all we have on Android is an operation
that prevents future write mappings. Therefore, this allows an existing
writeable mapping to be retained, but if that is unmapped then even the
parent process can't re-create it.
As with freezing, the read-only restriction may not be enforceable if
the recipient process isn't adequately sandboxed (e.g., on Linux, if it
can use /proc/self/fd to reopen the inode for writing).
