and can be removed. This patch removes all references to both the flag
and the process.

Drop unnecessary EventTarget::isFiringEventListeners() flag. This flag was checked by
our GC logic to avoid collecting wrappers while they are firing events. However, those
checks are in hot code paths and it should be up to the code dispatching the event
to keep the wrapper alive, either via ActiveDOMObject or GCReachableRef.

1. In SecureARM64EHashPins::keyForCurrentThread(), there's no need to add 1 to
   the value retrieve from TPIDRRO_EL0.  TPIDRRO_EL0 is a pointer to valid memory
   and can never be 0.  Also, we already code in multiple other places where we
   expect to load from it without a null check.

2. SecureARM64EHashPins::forEachPage() should use a do-while loop instead of a
   for loop.  This is because we are guaranteed to at least have 1 page at
   start up if the JIT is enabled.  If the JIT is not enabled, this code will
   never be called.

This reverts the functional part of r290995 for OSes what don't have an NSURLSession WebSocket implementation we can use.
The rest of r290995 was just moving UTF-8 encoding to a different location in the pipeline, which has no observable behavior change.

It is unfortunate, but our old implementation of WebSockets that uses CFWriteStreamWrite thinks it has written immediately,
so if I make SocketStreamHandleImpl::platformSend call m_client.didUpdateBufferedAmount even when bytesWritten >= length,
I don't have the bufferent amount updated synchronously like Chrome, Firefox, and the NSURLSession-based implementation have.
If I leave it as it is now, the buffered amount never goes back down to zero sometimes after writing to the stream.

It was broken before, it is differently broken now, and this restores the status quo on Big Sur.  This is why we can't have nice things.

Currently UI process sends PrepareToSuspend when a process has no activity that needs an assertion, or when
assertion will be invalidated due to timeout (when assertionWillInvalidate is called). On receiving PrepareToSuspend,
process will perform necessary actions, such as suspending storage threads for network process. According to crashes in
rdar://problem/92228190, the message is not received by process before suspension, or process gets suspended while
processing the message. To fix the crash, we need to ensure the message gets processed before process suspension.

This patch introduces ProcessStateMonitor that tracks when UI process will be suspended, and notifies WebProcessPools
when remaining running time is less than 15s. On receiving the notification, ProcessThrottlers of web processes will
invalidate activities and send out PrepareToSuspend messages to web processes. These processes are not allowed to take
new background assertion until ProcessStateMonitor finds process becomes running without timeout, or ProcessStateMonitor
is destroyed. ProcessStateMonitor is created when UI process enters background, and destroyed when UI process enters
foreground, to avoid getting receiving too many unnecessary updates from runningboardd.
