Adopt from Tor #16337.
This patch makes Animation API to report a rounded time when 'privacy.resistFingerprinting'
is true. The Animation API uses AnimationUtils::TimeDurationToDouble() to convert
its time duration into a double value and reports it when someone tries to query
time through Animation API. So, we use nsRFPService::ReduceTimePrecisionAsMSecs()
inside this method to round the time in the scope of the millisecond.

As part of the normalization process for WebExtension API calls, we need to
extract and validate the full set of value properties (including properties
X-rays would normally deny access to) from cross-compartment objects. This
currently involves waiving X-rays, enumerating property descriptors, and
unwaiving X-rays - all through X-ray wrappers and waivers - and generating a
lot of expensive and short-lived wrappers in-between.
This helper reads out the list of safe properties from within the object's
compartment, and then copies them over to an object in the target compartment,
without any X-ray overhead, or any unnecessary intermediate wrappers or
compartment switches. It cuts about 40% off the overhead of our normalization
code.

In the code that I'm profiling, the XPC WrappedNative overhead of calling
these functions adds up to about a quarter of the time spent executing the
code. The overhead of the WebIDL versions is negligible.

There is no reason that SetTextRangeStyle is defined at nsISelectionPrivate. Also, SetTextRangeStyle isn't scriptable, and is called from CompositionTransaction::SetIMESelection only. So we should move this to Selection.

In the patch2, we would honestly return the value of playback rate.
* test_info_leak.html/test_load.html
According to [1], we should only dispatch event "ratechange" when playbackRate or
defaultPlaybackRate attribute has just been updated. In these tests, they didn't
change the playbackRate or defaultPlaybackRate, we should not expect for the
"ratechange" event.

We allow swapping frameloaders between unrelated documents, so we need to
reparent wrappers when the owner content changes.

XPConnect wrapper overhead for this interface has been showing up heavily in a
lot of my profiles, in some places accounting for 50ms of the 80ms we spend
getting getting <browser> messageManagers. This improves the situation
considerably.

There are two overloads of nsSVGLength2::GetAnimValue:
1. float nsSVGLength2::GetAnimValue(nsSVGElement*) const;
2. float nsSVGLength2::GetAnimValue(SVGSVGElement*) const;
In Bug 265894, I created SVGViewportElement as a base class of SVGSVGElement.
SVGSVGElement::GetViewBoxTransform was moved to SVGViewportElement in that
refactoring. The local variable 'ctx' in that function was changed from
SVGSVGElement to SVGViewportElement, which when passed to
nsSVGLength2::GetAnimValue caused us to switch from calling the overload that
takes a SVGSVGElement to the overload that takes a nsSVGElement, which is not
what we want.
This patch changes the argument type of the nsSVGLength2::GetAnimValue overload
that takes an SVGSVGElement to take an SVGViewportElement instead, which causes
the GetAnimValue(ctx) calls in SVGViewportElement::GetViewBoxTransform to call
the correct GetAnimValue overload again.

This is straightforward, with only two notable things.
- `#include "nsXPIDLString.h" is replaced with `#include "nsString.h"`
throughout, because all nsXPIDLString.h did was include nsString.h. The
exception is for files which already include nsString.h, in which case the
patch just removes the nsXPIDLString.h inclusion.
- The patch removes the |xpidl_string| gtest, but improves the |voided| test to
cover some of its ground, e.g. testing Adopt(nullptr).

We should not be declaring forward declarations for nsString classes directly,
instead we should use nsStringFwd.h. This will make changing the underlying
types easier.
