This makes the naming more consistent with other functions called
Insert and/or Update. Also, it removes the ambiguity whether
Put expects that an entry already exists or not, in particular because
it differed from nsTHashtable::PutEntry in that regard.

There are no code changes, only #include changes.
It was a fairly mechanical process: Search for all "AUTO_PROFILER_LABEL", and in each file, if only labels are used, convert "GeckoProfiler.h" into "ProfilerLabels.h" (or just add that last one where needed).
In some files, there were also some marker calls but no other profiler-related calls, in these cases "GeckoProfiler.h" was replaced with both "ProfilerLabels.h" and "ProfilerMarkers.h", which still helps in reducing the use of the all-encompassing "GeckoProfiler.h".

For simplicity, this implements just on in `NO_TASKS` (the default) or
on in `ALL_TASKS` (opt-in). This disables all category registrations
when in background task mode; we'll selectively re-enable things as
appropriate.
The flag constants were chosen to smoothly extend to a (16-)bit set in
the future, should we want to add a `JUST_TASKS("task", "other-task")`
option in the future.
This also adds ython tests for gen_static_components.py exercising
categories, simply 'cuz it's easiest to see what this adds in such
tests. Functional tests will follow in patches that actually
implement the new background tasks functionality.

This allows to filter chrome manifest registration by the current
background task(s, in the future). Filtration behaves just like
filtering by "application":
* filter with `backgroundtask=` means disable for all background
tasks, since no background task will match ""
* filter with `backgroundtask!=` means enable for all background task,
since every background task will not match ""

If the implementation of an XPCOM service constructor involves dispatching an
event to another thread and blocking the current thread on that event, a
deadlock can occur if the target thread is also attempting to obtain that
service at the same time.
For instance, say nsIExampleService needs to be constructed on the main thread,
but some code in thread T is attempting to get a handle on it. Suppose the
implementation checks which thread it's running on and dispatches a synchronous
event to the main thread to do the actual construction work in the case that it
is not on the main thread. Further suppose that before that event is run, other
code on the main thread also attempts to get a handle on nsIExampleService. The
XPCOM service machinery sees that another thread is in the process of
constructing nsIExampleService, so it must wait for that to complete. However,
the thread that is attempting to do this construction is waiting for an event
to be run on the main thread. Thus, these two threads are deadlocked.
Before this patch, the XPCOM service machinery worked around this problem by
processing events on the second thread until it could proceed. However, this
caused a nested event loop, which is bad for stability because all guarantees
relating to when events will run are violated. In particular, this could cause
reentrency into the TLS implementation, which is not expected and has caused
intermittent crashes.
This patch removes the nested event loop in
nsComponentManagerImpl::GetServiceLocked in favor of not synchronously
dispatching events in XPCOM service constructors. One way to fix such
constructors is to move the event dispatch and blocking outside of the XPCOM
service machinery. See the other patch in this bug for an example.

These files were omitted from the original patch because reformatting them required some manual intervention in order to avoid breaking unit tests. Generally the `noqa` lines were already there and just needed to be moved from one line to another (due to the reformatting by `black`), but sometimes `black` saw fit to move a bunch of stuff all onto one line, requiring me to introduce new `noqa` lines.
Besides the autoformat by `black` and some manual fixups, this patch contains no other changes.

Allow-list all Python code in tree for use with the black linter, and re-format all code in-tree accordingly.
To produce this patch I did all of the following:
1. Make changes to tools/lint/black.yml to remove include: stanza and update list of source extensions.
2. Run ./mach lint --linter black --fix
3. Make some ad-hoc manual updates to python/mozbuild/mozbuild/test/configure/test_configure.py -- it has some hard-coded line numbers that the reformat breaks.
4. Make some ad-hoc manual updates to `testing/marionette/client/setup.py`, `testing/marionette/harness/setup.py`, and `testing/firefox-ui/harness/setup.py`, which have hard-coded regexes that break after the reformat.
5. Add a set of exclusions to black.yml. These will be deleted in a follow-up bug (1672023).

The `category.WithOptions(...)` syntax was a bit strange and difficult to explain.
Now the category and options are separate parameters. Default options can be specified with `MarkerOptions{}` or just `{}`.
As a special case, defaulted-NoPayload functions don't need `<>`, and defaulted-NoPayload functions and macros don't even need `{}` for default options, e.g.:
`profiler_add_marker("name", OTHER); PROFILER_MARKER_UNTYPED("name", OTHER);`

This backs out all work from bug 1627075 as well as all of its
descendents. There were a few conflicts when backing this out but
overall it was pretty clean, so I would say it's a fairly mild
level of risk. Historically Nathan Froyd has reviewed these patches,
but he is no longer at Mozilla, and no one else is particularly
familiar with the code, so I am passing this off to RyanVM who has
at least been familiar with the history of the bug.

The name `AUTO_PROFILER_MARKER_TEXT` is more consistent with the equivalent non-`AUTO` macro, and similarly arguments have been re-ordered to be the same, i.e.: Name, category&options, text.
The different macros with different argument sets can now be collapsed into one macro, and the optional arguments (timing, inner window id, backtrace) can easily be added to the `MarkerOptions` where needed.
As a bonus, a specific start time can optionally be provided at construction time.

* Use clearer pref names.
* Default (and only support) IPDL dispatching.
* Make DispatchCommands async-only.
* Sync ipdl command per sync webgl entrypoint.
* Eat the boilerplate cost, since there's not too many.
* Run SerializedSize off same path as Serialize.
* All shmem uploads go through normal DispatchCommands.
* Defer pruning of dead code for now so we can iterate quickly.
* Use Read/Write(begin,end) instead of (begin,size).
* This would have prevented a bug where we read/wrote N*sizeof(T)*sizeof(T).

This builds on the existing static components infrastructure to allow defining
a Services.jsm-type services cache with no runtime memory overhead for any
services until they're accessed.
Any class entry with a 'js_name' attribute automatically becomes available on
the services cache with that name, and any interfaces listed in its
'interfaces' list are automatically queried on it.
