When we had it in the loop, we would continually reduce it, which held the
possibility of bumping it down an epoch due to double imprecision. Now
we only reduce it once, using all rAF callbacks get the same timestamp.

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).

In Bug 1387894 we created a mode for Firefox where it unconditionally clamps all timestamps to 20 microseconds. This happens if you disable privacy.reduceTimerPrecision (which is on by default) and is so we don't inadvertently leak super-high-resolution (nanosec) timestamps.
As part of that patch, we started clamping animation timestamps - which are exempted from privacy.reduceTimerPrecision because it was too difficult to get them working at the time. (We should still fix that though.)
This caused new test failures, and one of those was a comparison between document timelines and the timestamp in requestAnimationFrame. we were not clamping the timestamp in requestAnimationFrame under the logic that it fires in predictable intervals.
However discussions about the WPT change we made to 'fix' the now-broken comparison https://github.com/web-platform-tests/wpt/pull/18172 and https://github.com/web-platform-tests/wpt/pull/18357 showed me that document.timeline is supposed to be slaved to the requestAnimationFrame timestamp (or vice versa.)
The correct fix is therefore to unconditionally clamp the requestAnimationFrame timestamp AND the document.timeline timestamp. In doing so we also start clamping/jittering the requestAnimationFrame timestamp in Resist Fingerprinting mode, so that might cause some new/unexpected behaviors for that mode we should watch out for.

This avoids doing wasted work and sending spurious resize
events if this case would be hit.
In practice, it cannot be hit yet, I think, because
callers do check for this and bail out earlier. But
there's no assertion to that respect so this shouldn't
hurt.

This condition was needed when FindInsertionPrevSibling and co didn't understand
display: contents.
Editor is pretty broken (and calls into PresShell::ContentRemoved directly, and
incorrectly, using anonymous nodes).
In this case we were taking the XBL path because of display: contents, which
means that we tried to seek to the editor anonymous node, and crash (since it's
not an explicit kid).
Editor needs to get fixed, but this is technically more correct and fixes the
crash, so we may as well take it in the interim.

When contents notify IME or requests something to IME, they need to use
an `nsIWidget` instance which may have focus if active, and handles
native keyboard/IME events since that knows correct native IME context.
Currently, such widget exactly matches with the result of
`nsPresContext::GetRootWidget()`. However, this is unclear for most developers.
Therefore, this patch creates a wrapper method of it named
`nsPresContext::GetTextInputHandlingWidget()`. Then, also adds
`BrowserParent::GetTextInputHandlingWidget()` wraps it. Finally, makes
`IMEStateManager` call `GetTextInputHandlingWidget()` of them.

Resolution is at:
* https://github.com/w3c/csswg-drafts/issues/3779#issuecomment-481762912
Tests are at https://chromium-review.googlesource.com/c/chromium/src/+/1547974,
I'll make sure to wait until they're in the tree and ensure they're passing.
Note that we need to ensure in the frame constructor that the document element
is styled _before_ calling UpdateViewportScrollStylesOverride(). This saves
duplicated work (since ResolveStyleLazily throws away the style).
ResolveStyleLazily already returns out of date styles, unless the element is not
styled yet, or is in a `display: none` subtree, in which case it computes and
returns a new (up-to-date) style.
So the switch to the FFI call only should change behavior for the display: none
subtree case (since we ensure the unstyled case isn't hit by styling the
document earlier). But that case is one of the cases we're interested in
changing, conveniently.

Return a raw pointer instead of a strong reference to a ComputedStyle, and
handle the case of the style not being present by returning null rather than
requiring an extra function to check it and crashing if the precondition is not
met.
Also, name them so that it's clear they just return outdated styles and don't
make any extra effort.
This is just cleanup that makes the next patch easier / more obvious.
