[root layer scrolls] Rebaseline 4 passing tests

These tests just needed a simple invalidation type change. The
expectations for those invalidations now match non-rls:
paint/invalidation/svg/feImage-target-reappend-to-document.svg
paint/invalidation/svg/feImage-target-add-to-document.svg

These tests had rls-specific expectations that had an inner-editor
that is not present in the actual test. These now match non-rls:
paint/invalidation/textarea-set-disabled.html
paint/invalidation/textarea-caret.html

[root layer scrolls] Fix subpixel-shadow-included-in-invalidation.html

This test depends on invalidations on a specific layer. With root layer

scrolling contents layer which is not the first layer.

[root layer scrolls] Rebaseline 2 passing tests

These tests had rls-specific expectations that had an inner-editor
that is not present in the actual test. These now match non-rls.
This is a followup to [1] and should be the last of the
inner-editor baselines.

[root layer scrolls] Invalidate scrolling contents on size changes

This patch factors ViewPaintInvalidator into BoxPaintInvalidator
which reuses BoxPaintInvalidator's logic for invalidating the
scrolling contents layer. This fixes one root layer scrolling test.

[root layer scrolls] Fix 2 paint invalidation tests

The RLS baseline was wrong and we now match non-RLS except with
a scrolling content layer:
paint/invalidation/table-two-pass-layout-overpaint.html

This test was looking for paint invalidations on the root layer
but needed to use the scrolling contents layer with RLS:
paint/invalidation/media-audio-no-spurious-repaints.html

This test was recently rebaselined in

[root layer scrolls] Invalidate on LayoutView style changes

The document element propagates styles to the LayoutView (see
Document::PropagateStyleToViewport) but the LayoutView was early-
outing before fully handling these style changes. In particular,
background color changes did not set
SetBackgroundChangedSinceLastPaintInvalidation.

It does not seem like this code needs to early-out when !parent.
This early-out was added in [1].

[root layer scrolls] Use layout overflow for background invalidation

When the LayoutView uses a background from the document element, and
one of the background layers uses local geometry, a change in the
document element's layout overflow, not size, should invalidate the
background. Using ShouldFullyInvalidateBackgroundOnLayoutOverflowChange
generates invalidations on layout overflow location changes which is
new for the LayoutView and fixes an existing invalidation bug.

This patch adds an invalidation test where the layout overflow changes
but the size remains static. Before this patch, the test would crash
with root layer scrolling due to underinvalidation.

This patch also adds an invalidation test where the layout location
changes but the size remains static. Before this patch, the test would
fail with and without root layer scrolling.

The change in BoxPaintInvalidatorTest.NonCompositedLayoutViewGradientResize
from kBackground to kGeometry is not obvious. Before this change, the size
change was detected in ViewBackgroundShouldFullyInvalidate even though the
background did not need to be fully invalidated, which resulted in
kBackground. With this change, the background does not need an invalidation
and the size change is detected later in ComputePaintInvalidationReason
which results in kGeometry.

[root layer scrolls] Rebaseline 2 passing invalidation tests

Just needed a mac10.11-specific baseline (non-RLS also needs this):
paint/invalidation/background/change-text-content-and-background-color.html
The difference is:
-          "rect": [30, 30, 45, 23],
+          "rect": [30, 30, 44, 23

Just needed a fixed win10 baseline:
paint/invalidation/selection/japanese-rl-selection-clear.html
The difference is:
-          "rect": [230, 123, 542, 394],
+          "rect": [273, 123, 499, 394],

[root layer scrolls] Relayout after scrollbars change

Without root layer scrolling (RLS), the LayoutView is laid out a second
time after scrollbars change in LocalFrameView's ScrollbarExistenceMaybeChanged.
With root layer scrolling we instead do a nested layout through
PaintLayerScrollableArea's UpdateAfterLayout. Before this patch, the nested
layout for root layer scrolling did not invalidate SVG after the widths changed.

https://chromium.googlesource.com/chromium/src/+/e3276a9902608cd3930d2a1dad67d56b5ae98313
This patch updates the RLS expectation too.

http/tests/devtools/agents-enable-disable.js (and virtual variant):
This test is crashing on all platforms but the expectation was marked as
timeout on just mac.

plugins/mouse-events-fixedpos.html:
This test is crashing flakily (see:  https://crbug.com/786117 ).

To make it easier to update the expectations file, a new section for
flaky tests has been added.

Do not invalidate solid color backgrounds on location changes

[1] introduced a perf regression because it caused background
invalidations whenever the layout overflow's location changed.
This is needed for cases such as gradients, but is not needed in
the common case of solid color backgrounds.

This patch adds logic to not invalidate backgrounds on location
changes when the background is solid color and fully covers the
layout overflow area. This required extracting the incremental
invalidation logic out of ShouldFullyInvalidateBackgroundOnLayoutOverflowChange
so the function now returns true for background changes only.

This restores the following tests to their baselines before [1]:
paint/invalidation/overflow/justify-items-overflow-change.html
paint/invalidation/overflow/justify-self-overflow-change.html
paint/invalidation/position/transform-absolute-child.html
paint/invalidation/transform/transform-rotate-and-remove.html
paint/invalidation/offset-change-wrong-invalidation-with-float.html

[root layer scrolls] Cleanup composited-iframe-scroll-repaint-iframe.html

paint/invalidation/composited-iframe-scroll-repaint-iframe.html was
added in [1] as a test of composited iframe scrolling and used an
overflow: hidden scroller. With Root Layer Scrolling (RLS),
overflow: hidden no longer composites (see discussion in
 https://crbug.com/784053 ) so this test does not work.

This patch updates the test to use overflow: scroll and adds a style
for hiding the scrollbars. There is no change in behavior for the
non-RLS codepath, but with this change the test now works for RLS.

[PE] Remove extra iframe invalidation on slow scrolls

LocalFrameView::ScrollContentsSlowPath had an invalidation for
iframes but this invalidation was already handled will full
invalidation. This patch removes this extra invalidation.

This makes the root layer scrolling (RLS) and non-RLS
expectations match because this extra invalidation was not
issued for RLS.
