We were keeping nsDocShell::mHistoryId and nsDocShell::mOSHE as keys. They
weren't quite good because:
1. While loading an iframe, they were being registered twice with the same
ids(for about:blank and the real URL) sometimes.
2. It wasn't possible to access to the parent mHistoryId and mOSHE from a child
processes if the parent is in a different process. That may not be the case for
now, but it will be after fission.
So we had to find other IDs to:
1. Determine the Tab of the frames.
2. Determine the URLs of the frames.
For the first use case, we were using nsDocShell::mHistoryId for that purpose
but that was wrong. The closest thing that we can get to a tab ID is
BrowsingContext ID because they don't change after a navigation. But iframes
have different BrowsingContext's, so we still need to create a tree to
construct a tab content. That can be either in the front-end or capture time.
For the second use case, we were using a key pair of mHistoryId and mOSHE. We
now chose to keep inner window IDs for that purpose. Inner window IDs are
unique for each navigation loads because inner window correspond to each JS
window global objects. That's why we can use that without any problem. But one
problem is that we cannot handle `history.pushState` and `history.replaceState`
changes with that change since window global objects won't change during those.
But that was the best thing we can do after fission. So this will be a small
sacrifice for us to keep that functionality working after fission.
In that patch we also remove the registration/unregistration calls. We are
going to add those calls in the next patch.

In places where profiler_is_active() was used around a profiler_add_marker() (or
similar) call, replace it with profiler_can_accept_markers().

All calls to `profiler_add_marker()` (outside of the profilers code) are
now replaced by either:
- `PROFILER_ADD_MARKER(name, categoryPair)`
- `PROFILER_ADD_MARKER_WITH_PAYLOAD(name, categoryPair, TypeOfMarkerPayload,
(payload, ..., arguments))`
This makes all calls consistent, and they won't need to prefix the category pair
with `JS::ProfilingCategoryPair::`.
Also it will make it easier to add (and later remove) internal-profiling
instrumentation (bug 1576550), and to replace heap-allocated payloads with
stack-allocated ones (bug 1576555).

While in theory
ReducetimePrecision(x) == ReducetimePrecision(ReducetimePrecision(x)
this is not always the case. Sometimes ReducetimePrecision(x) is only representable
as an epsilon below the target rounding; resulting in a second call causing
an unintentional additional reduction.
A performance entry's duration was one such place we were calling the reuction
function twice. We can remove one of those calls and just ensure that the original
entries are reduced. (They mostly were, except for one instance.)

We unconditionally clamp all times to 20us and not just performance.now()
This will consistently apply a 'safe' minimal clamping (it's not safe but
I guess it's safer than ns-level precision) to all timestamps, and remove
intermittents that are caused by comparing a clamped performance.now() to
an unclamped [something else].

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.

1: Correct the Performance API 'NowUnclamped' to obtain a non-Fuzzed Timestamp
2: Do not compare fuzzed and non-fuzzed timestamps in a Refresh Driver assert,
since this happens so early on that we will eventually compare them and
asserting would be bad.
We attach it to WorkerPrivate and DOMNavigationTiming so it will be re-used
when it should.
WorkerPrivate is used in the Performance APIs, Performance Storage Worker,
and Event.
DOMNavigationTiming is used only in the Performance APIs, but the crucial
part is that when the individual DOMNavigationTiming object is re-used,
so will the context seed. This in particular came up with the
nav2_test_document_open.html Web Platform Test which illustrated the fact
that even if you .open() a new document, the performance navigation data
is not supposed to change.

PresShell only uses performane.now to track refresh times, and notify internal
observers. We can provide more accurate times by not clamping and jittering
these numbers.
