* Fix code that deregisters the Atom Scene subsystem from the AzFramework Scene
The AzFramework Scene subsystem API is a generic container based on the
type of argument that is passed to it. It maintains a vector of typeids,
and only one object of any type is stored at a time. The Bootstrap system
component registers the Atom scene as a `ScenePtr` (aka
`AZStd::shared_ptr<RPI:Scene>`) with the AzFramework Scene's generic
subsystem. However, the component was previously deregistering the type by
value, `RPI::Scene`. Since no subsystem for the type `RPI::Scene` was set,
unsetting this type did nothing. The result was that the `RPI::Scene`
object would still be around by the time that all the Atom
`InstanceDatabse`s were being destroyed, resulting in a large number of
errors reported about leaked instances during global shutdown.
This fixes the above issue by passing the `m_defaultScene` as a parameter
to `AzFramework::Scene::UnsetSubsystem`, the same value that is passed to
`SetSubsystem`. This is better, because instead of providing explicit
template arguments (which were specifying the incorrect type), this now
allows the compiler to deduce the correct type, and the syntax is symmetric
with the call to `SetSubsystem`.

* Correctly release the AWS API from the `HttpRequestManager` module
This code was incorrectly assuming that
`AWSNativeSDKInit::InitializationManager::Shutdown()` would be called
automatically by the `InitializationManager` itself. However, all that
`InitAwsApi()` does is create an `AZ::EnvironmentVariable`, which is a
ref-counted type, and stores it in a global static. That global static is
defined in a static library (namely `AWSNativeSDKInit`), which is linked
in to the `HttpRequestManager` dynamic lib. Because it is a global static,
it has to be explicitly cleared with the call to `Shutdown()`. Otherwise
the destructor of the EnvironmentVariable doesn't happen until global
destruction, by which time the allocator that is supplied to the AWS SDK
has already been destroyed, and the shutdown of the AWS SDK attempts to use
the already-destroyed allocator.

* Avoid blocking the remote console server thread if there are no connections
The Remote console server runs in a separate thread. Previously, it would
directly call `AzSock::Accept()` and block the server thread until some
client connected to it. However, if no client connected, the thread would
continue to be blocked, even if the game launcher tried to exit.
This adds a check to see if there's a client on the socket before calling
`Accept()`, to avoid the deadlock on launcher exit.

* Allow pumping the event loop to close the launcher window
Events from the OS are handled in the game's main loop. The general loop
looks like this:
* Read events from the OS
* Tick the game application
One of the events that can come from the OS is that the window hosting the
game is closed. When this event happens, many resources provided by the
renderer are freed, and the game application's `shouldExit` bit is set.
However, when the game's `Tick()` is called, there is lots of code that
assumes the renderer is still there. To avoid crashing in the `Tick()`
call, check if the game should exit after pumping the system events.

* Unload the level when exiting the launcher
This ensures that any resources held onto by the level are freed before the
launcher exits.

* Add an explicit bus `Disconnect()` call to `AZCoreLogSink`
This is necessary because this bus has virtual functions and can be called
from multiple threads.

* Allow normal cleanup to take place when exiting the game launcher
Previously, global cleanup was side-stepped by calling `TerminateProcess`
or `exit`, when quitting the game launcher. This is in contrast to the call
to `_exit` on Linux and Mac when exiting the Editor. That leading `_` makes
a big difference: the former runs object destruction, the latter does not.
Instead of making the launcher exit with `_exit` on Linux, instead, remove
that call and actually run all the atexit code.
This does not modify the Editor's behavior however. It still uses `_exit`
and `TerminateProcess`.
