This member was never changed after it was set, but it couldn't be const
because WorkerLoadInfo used a custom StealFrom() function instead of an
idiomatic move constructor and move assignment operator. This commit
replaces StealFrom with its idiomatic counterparts, adds a function that
determines a new worker's secure context status, and uses that function
to initialize the now const mIsSecureContext.
Making constant members const is part of a greater effort to ensure that
data is either modified from a single thread only, or access to it is
synchronized properly.

Remove WorkerPrivate::mQueuedRunnables and its associated functions. The
approach they implement can never be correct, as the parent window gets
'resumed' whenever the debugger resumes execution after a breakpoint. The
interrupted JavaScript invocation has not yet completed, so it is not yet time
to run mQueuedRunnables. Simply re-enqueing them at that point can cause
messages from the worker to arrive out of order.
Instead, we create a separate ThrottledEventQueue,
WorkerPrivate::mMainThreadDebuggeeEventTarget especially for
WorkerDebuggeeRunnables, runnables sent from the worker to the main thread that
should not be delivered to a paused or frozen content window. This queue is
paused and resumed by WorkerPrivate::Freeze, WorkerPrivate::Thaw,
WorkerPrivate::ParentWindowPaused, and WorkerPrivate::ParentWindowResumed.
Since this affects when WorkerDebuggeeRunnables are delivered relative to other
administrative worker runnables, WorkerDebuggeeRunnable must use a
ThreadSafeWorkerRef to ensure that the WorkerPrivate sticks around long enough
for them to run properly.

This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..

PerformanceCounters are currently disabled in two ways:
- a preference that's off by default "dom.performance.enable_scheduler_timing"
- calls made only for nightly using #ifndef RELEASE_OR_BETA
In order to simplify the code, let's remove the #ifndef and rely only on the pref.
That will also allows us to use the feature in every version going forward.
The performance will not be impacted since the current code is already using
the (cached) pref value to determine if the counters are used.

Chromeutils.RequestPerformanceMetrics() is now composed of two parts:
- calls content processes via IPDL to get their counters
- directly dispatch counters from the parent process

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.

Adds a PeformanceCounter class that is used in DocGroup and WorkerPrivate
to track runnables execution and dispatch counts.
