[SPv175] Support incremental invalidation on scrolling contents layer

When the scrolling contents layer is resized and it paints the
background, we should invalidate the expanded/shrunk part of the
background. For SPv1 this is done by calling IncrementallyInvalidatePaint.
For SPv175 we need to pass kIncremental reason to PaintController.

The remaining issue is for SPv2 only.

The root cause seems about painting which caused the invalidation issue.

We need a special DisplayItemClient for the background painted on the scrolling contents layer.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/4970db683f2db95e6d638af2c6cc3f489a19d217

[CI/PE] Cleanup background paint invalidation

- Replace LayoutObject::SetBackgroundChangedSinceLastPaintInvaldiation()
  with LayoutObject::SetBackgroundNeedsFullPaintInvalidation().

  - Previously we used SetShouldDoFullPaintInvalidation(
    PaintInvalidationReason::kBackground) in some cases, but it may miss
    invalidation of background painted on the scrolling contents layer.
    Now use the new method in all cases that the background needs full
    paint invalidation.

- Move all view background paint invalidation into BoxPaintInvalidator.
  This simplifies the call sites which now just call
  SetShouldCheckForPaintInvalidation(), and make it possible to do just
  incremental invalidation instead of full invalidation when the browser
  control hides and background at the bottom appears on Android.

- Other cleanups

- New tests

This is a preparation for SPv2 scrolling background invalidation.

[CI] Combine GetBackgroundPaintLocation of PaintLayer and LayoutBoxModelObject

For fixing SlimmingPaintV2 scrolling background painting and
invalidation, we need a single place to get the accurate value
of the background paint location.

Revert "[CI] Combine GetBackgroundPaintLocation of PaintLayer and LayoutBoxModelObject"

This reverts commit af460e9a5c4ac34692ffa109e87f744ce082b5c0.

Reason for revert:
Seems to have broken paint/invalidation/table/cached-69296.html from webkit_layout_tests on Mac 10.11 - currently failed 7/7 times after this landed:
https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Mac10.11%20Tests
First failing build:
https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Mac10.11%20Tests/30030

Reland "[CI] Combine GetBackgroundPaintLocation of PaintLayer and LayoutBoxModelObject"

This reverts commit 0c3cbcc16d0bca1952b75fb5b6cada8285108f37.

Reason for revert: Looks like this was a false positive; the test has failed again after the revert.

Use a special display item client for scrolling background

Scrolling background is the background painted on the scrolling contents
layer. Previously we used the scrolling contents graphics layer as the
display item client to give the background proper visual rect, but that
didn't work for SPv2 which doesn't have the graphics layer.

Now use a special display item client for scrolling background.

This is a prerequisite of fixing SPv2 scrolling background.

[SPv2] Fix paint and invalidation of scrolling background

In SPv1, background painting on the main graphics layer and on
the scrolling contents layer are initiated by CompositedLayerMapping
separately, so BlockPainter::Paint() just check the context to paint
the background once on either the main graphics layer or the scrolling
contents layer.

In SPv2, for background painting BlockPainter::Paint() is called only
once for each object in the background paint, so it needs to deal with
the background on the main graphics layer and on the scrolling contents
layer at the same time.
