This PR reverts a few widgets back from #167784, so that they draw RRect instead of RSuperellipse. These shapes are either too small to make a difference between the two shapes, or indifferent at all. After observing how costly RSuperellipses are on Web, I decided that this is a good compromise.

LGTM. Looks like the analyzer just doesn't like some formatting.

I wonder if web continues to be an issue if we should consider adding a flag to enable/disable RSupereliipse for these widgets?

@MitchellGoodwin If we can't afford squircle on Web at all we can simply keep their drawing ops as RRects (instead of doing it at the widget level), but it seems that the Web team was ok with squircles. Let's see how they perform.

[Cupertino] Make some widgets no longer use RSuperellipse (flutter#17…
97f85b7 
…1830)

This PR reverts a few widgets back from
flutter#167784, so that they draw
`RRect` instead of `RSuperellipse`. These shapes are either too small to
make a difference between the two shapes, or indifferent at all. After
observing how costly RSuperellipses are on Web, I decided that this is a
good compromise.
