5064532: GridLayout with initial "stretchy" row and "gone" view in last row doesn't stretch properly
Also:
. Infer stretchibility from whether or not gravity is defined.
. Make algorithms for handling flexibility within cell groups consistent
with those acting between cells groups (via constraint system).
. Hide and deprecate methods taking flexibility argument.
. Hide and deprecate CAN_STRETCH constant.
Both deprecated features will be removed after references are removed from platform.

A cell's ability to shrink or stretch is now integrated with the
constraints system, which is now supplied with both upper and lower
bounds.
Also:
. Remove package private access (pseudo) annotation
. Remove rowWeight and columnWeight attributes and fields
. Remove code to handle weights
