initialDateTime should account for minuteInterval

Add golden tests for CupertinoDatePicker

Thanks to cbracken@'s suggestion on another Google-internal change.

RenderTable._computeColumnWidths() had a logic error that caused flex columns to be collapsed to their minimum widths in certain situations dependent on the layout width constraint and the number of flex columns.

Bumps the Android build tools to 28.0.3 instead of 28.0.0 in the Dockerfile, since that is what flutter doctor wants.

* Check for invalid elevation usage in the layer tree

This reverts commit 949023b2.

This reverts commit a8211369.

* Remove pressure from PointerHoverEvent ctor
