This PR does two things:
- It allows BottomAppBar to have a custom shape even when it doesn't
have a notch.
- It adds AutomaticNotchedShape, an adapter from ShapeBorder to
NotchedShape.
In certain situations, a developer may require the border of a Material to be painted behind its child. For example a Card widget that has a full width image across the top half. In that scenario, the image should ideally be painted above the border with regards to z-position.
This change exposes a flag on Material widget to achieve this behavior. Additionally, the same flag is exposed on Card widget to allow the Card widget to pass this down to its Material.
I added a couple golden tests to verify this new behavior. Goldens are here:

Previously, a disabled floating action button always had zero
elevation, which looks dumb.
This also fixes the issue whereby highlightElevation was not honoured
on floating action buttons.
This also fixes an issue I found during testing whereby setState was
being called during build when onHighlightChanged fired due to
onPressed becoming null while a gesture is ongoing (which triggers an
onTapCancel synchronously during build).
* Added the superellipse (a.k.a. squircle) shape to flutter, which is needed to recreate some cupertino components, e.g. buttons in pixel-perfect detail (issue #13914).
Should fix#22226.
Code introduced in #20890 caused a regression that broke color flooding animations in a BottomNavigationBar that has BottomNavigationBarType.shifting.
The original issue (#19653) dealt with background color changes not occurring until another tab was selected. The result is that the background color instantly changes whenever the state changes and when the widget changes, instead of allowing a new widget to animate the background color change.
And update goldens.

Goldens updated due to Skia AA changes. We previously also made a mistake by having a golden test run on MacOS.

Previously, the engine did not properly pass the AA flag on ClipRect.clipBehavior. flutter/engine#6199 fixes this and enables AA. However, default AA on clipRects has caused severe regressions in benchmark performance.
To maintain expected performance, we should now default the clipBehavior to hardEdge to disable default AA. This is consistent with any flutter projects that did not previously explicitly set the clipBehavior and should not change app appearance.
The average frame time of page transitions on Moto G4 is now very
close to 16ms (the last 10 measurements on our dashboard are
between 15.5ms to 16.7ms and half of them are below 16ms).
It is now much faster than when we disabled it (which was at about
35ms). So I think that we should be able to enable it by default.
I'll leave the flag there until we implement the retained rendering
to bring the frame time comfortably below 16ms.
