This pref does not override privacy.resistFingerprinting, but when it is set (and
privacy.resistFingerprinting is not) we will still adjust the precision of almost
all timers. The adjustment amount is the second pref, which is defaulted to
20us but now dynamically adjustable (in the scale of microseconds.)
This patch does _not_ address the performance API, which privacy.resistFingerprinting
disables.
We are landing this preffed on at the current value we clamp performance.now() at
which is 20us.

This is a follow-up to bug 1409249. There are a lot of places where our
factory singleton constructors either don't correctly handle their returned
references being released by the component manager, or do handle it, but in
ways that are not obvious.
This patch handles a few places where we can sometimes wind up with dangling
singleton pointers, adds some explanatory comments and sanity check
assertions, and replaces some uses of manual refcounting with StaticRefPtr and
ClearOnShutdown.
There are still some places where we may wind up with odd behavior if the
first QI for a getService call fails. In those cases, we wind up destroying
the first instance of a service that we create, and re-creating a new one
later.

This commit adds a paint worker thread pool to PaintThread, and dispatches
tiled paints to it. The thread pool is only created if tiling is enabled,
and its size is set by 'layers.omtp.paint-workers' and defaults to 1. If
-1 is specified, it will be sized to 'max((cpu_cores * 3) / 4, 1)'.
The one tricky part of dispatching tiled paints to a thread pool is the
AsyncEndLayerTransaction message that must execute once all paints are
finished. Previously, this runnable would be queued after all the paints
had been queued, ensuring it would be run after they had all completed.
With a thread pool, there is no guarantee. Instead this commit, uses
a flag on CompositorBridgeChild to signify whether all of the paints
have been queued ('mOutstandingAsyncEndLayerTransaction'), and after
every tiled paint it is examined to see if that paint was the last
paint, and if it is to run AsyncEndLayerTransaction. In addition,
if the async paints complete before we even mark the end of the
layer transaction, we queue it like normal.
The profiler markers are also complicated by using a thread pool.
I don't know of a great way to keep them working as they are per
thread, so for now I've removed them. I may have been the only
one using them anyway.

Most of the Shadow DOM related code are behind "dom.webcomponents.enabled" and
this pref is only used by Shadow DOM right now, so we should rename it to
"dom.webcomponents.shadowdom.enabled"

Mechanism for restricting pinch zooming when gesture is a two
finger pan. If the pinch span is below a given threshold and the
scroll distance above a given threshold then the zoom level is
maintained to allow for smooth panning with two fingers.

This patch introduces three keyed histograms:
- PREFERENCES_FILE_LOAD_SIZE_B
- PREFERENCES_FILE_LOAD_NUM_PREFS
- PREFERENCES_FILE_LOAD_TIME_US
They are all keyed on the prefs file's name; in my local Linux64 build there
are 13 such files.
Because prefs start up earlier than telemetry, we have to save the measurements
and then pass them to telemetry later.
