This commit adds categories to all markers. This way the profiler's
marker categories and frame label categories agree. There are a few
duplicate category properties on some of the marker payloads, but
this could be cleaned up in a follow-up if needed.

We can directly set environment variables for the child process on
all platforms now, instead of changing the parent's environment and
inheriting the changes. This simplifies memory management, but more
importantly it's necessary for thread safety to allow launching
processes from a thread pool.

Add a new class to extract tracelogger data using chunked buffers and use this to write the data out to the profiler JSON output. Copying the data in chunks lets us minimize our memory overhead when writing out to the profiler so a large array of millions of elements does not need to be allocated ahead of time.

This is a best effort attempt at ensuring that the adverse impact of
reformatting the entire tree over the comments would be minimal. I've used a
combination of strategies including disabling of formatting, some manual
formatting and some changes to formatting to work around some clang-format
limitations.

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.

before the dispatched job was run, and the time was zero and triggered an assertion.
This patch also includes more verbose logging for additional debugging.

Removing this field since we already have start/end time for each marker payloads.
Also we are assigning the same timestamp to them. We don't need to unnecessarily
duplicate the information here.
