This only changes the behaviour when called with a TaskQueue or other type
using SerialEventTargetGuard on the stack. They are being switched over as the
existing GetCurrentEventTarget method is being removed, as it is somewhat
confusing, and poorly documented.
Callers which need to get the current thread even when on a threadpool or
behind a TaskQueue were switched to GetCurrentEventTarget in the previous part.

This is no longer necessary as the Quantum DOM project is no longer
happening, and removing support simplifies various components inside of
IPDL.
As some code used the support to get a `nsISerialEventTarget` for an
actor's worker thread, that method was replaced with a method which
instead pulls the nsISerialEventTarget from the MessageChannel and
should work on all actors.

Before P1, GetCurrentThreadSerialEventTarget would have always returned the same data as NS_GetCurrentThread, making the comment incorrect Now it will properly return the running TaskQueue if any.
This change of name more clearly exposes what they are doing, as we aren't always dealing with threads directly; but a nsISerialEventTarget

For the Quatum DOM project, it's better to work in terms of event targets than
threads. This patch converts DOM code to operate on event targets rather than
threads, when possible.

We will use the new type for the generated IPDL message handler
prototype to make sure correct error handling method is called.

This change avoids lots of false positives for Coverity's CHECKED_RETURN
warning, caused by NS_WARN_IF's current use in both statement-style and
expression-style.
In the case where the code within the NS_WARN_IF has side-effects, I made the
following change.
> NS_WARN_IF(NS_FAILED(FunctionWithSideEffects()));
> -->
> Unused << NS_WARN_IF(NS_FAILED(FunctionWithSideEffects()));
In the case where the code within the NS_WARN_IF lacks side-effects, I made the
following change.
> NS_WARN_IF(!condWithoutSideEffects);
> -->
> NS_WARNING_ASSERTION(condWithoutSideEffects, "msg");
This has two improvements.
- The condition is not evaluated in non-debug builds.
- The sense of the condition is inverted to the familiar "this condition should
be true" sense used in assertions.
A common variation on the side-effect-free case is the following.
> nsresult rv = Fn();
> NS_WARN_IF_(NS_FAILED(rv));
> -->
> DebugOnly<nsresult rv> = Fn();
> NS_WARNING_ASSERTION(NS_SUCCEEDED(rv), "Fn failed");
