Current cache usage histogram is dominated by samples in the 0-1 range,
making percentile comparison difficult. This change prevents 0% samples
from recording to the metric
Renderer4.GpuImageDecodeState.CachePeakUsagePercent.

With this change, WebLayerShell now only depends on the weblayer/public

This change enhances the accessibility of the Network tool Timing tab
by making the following changes:

 - Add hidden global headers to give column context to screen readers
 - Slight modification of color contrast for section headers (> 4.5)
 - Updated "TIME" to "DURATION" to avoid confusion
 - Applied ARIA heading for soft headers
 - Restructured columns to remove empty table cells from being read
   by a screen reader
 - Added ARIA labels to waterfall column that
   read the start time of the request. (Column 3 indicates the
   duration of that part of the request timing).

This complicates the code a little bit. I don't think this is strictly
necessary, since the savings it would provide for the single frame are
defeated by the fact that we need to paint that frame, so we process
the lifecycle anyway. When intersection observer runs, we'll still
update the throttling status.

I've re-opened the referenced bug with hopes of coming up with (and
documenting) a good solution that would save us as much lifecycle
processing time as possible.

These tests were previously migrated from single-threaded MessageLoop to
a multi-threaded TaskEnvironment (then named ScopedTaskEnvironment) as
part of crbug.com/891670.

//base OWNERS decided in retrospect that it was better to keep a
single-threaded option for TaskEnvironment and introduced
SingleThreadTaskEnvironment. This CL retrofits that decision for
/content/browser/gpu.

This CL is a no-op if it passes CQ.

Custom scroll corners and resizers are LayoutScrollbarPart objects, they will
set scrollable container box as parent by calling SetDangerousOneWayParent.
By now, this one way parent is just used for getting the writing mode style.
