be safe to skip them when the profiler is paused; another bug should
investigate that.)

profiler_thread_is_being_profiled() checks if the profiler is active (quick
inline atomic check) and if the current thread is being profiled (function call
doing a TLS-atomic check).
This may be used instead of profiler_is_active() for thread-specific recordings
(e.g.: markers).

RacyRegisteredThread::IsBeingProfiled() is only true when the thread is being
actively profiled, i.e., it is in the selected-thread list and the profiler is
active (modulo racy accesses when starting/stopping the profiler, i.e., don't
rely on it if accurate concurrency is required).

This field is in addition to the existing process type fields we already have:
- profile.threads[i].processType contains the string for the GeckoProcessType.
- profile.threads[i].name contains the ThreadInfo name.

Added a mechanism to register and unregister the DocShells from the CorePS depending
on the state of the profiler. Registering mechanism is straightforward. During
unregistration, if profiler is not active, we remove the DocShell information
immediately. If profiler is active, we don't remove and we keep the profiler buffer
position at that moment. During another DocShell registration we Discard the
unregistered DocShells. If the profiler buffer position is greater than the position
when we captured during unregistration, we delete the DocShell since that means there
can't be any markers associated to this DocShell anymore.

JSONWriter currently calls new and delete indirectly through mozilla::MakeUnique to allocate a buffer. Becuase of this, the methods of this class cannot be invoked within Spidermonkey due to https://searchfox.org/mozilla-central/source/config/check_vanilla_allocations.py#6-14. Therefore, JSONWriter needs an AllocPolicy template parameter so that the allocation and deallocation routines can be changed to match the JS AllocPolicy when invoked within SpiderMonkey.
