camera2: Modify logic for comparing rects
The helper function expectRectsAreSimilar, used by
e.g. testDigitalZoom, is checking that the top-left
coordinates are similar with an error margin in percent.
However, this doesn't work well if the top-left
coordinate is only a few pixels since a pixel
difference is then significant amount in percentage.
For example, if the actual top-left is (6,3) and the
expected is (8,4), then the difference in percentage
is 25%.
Instead of comparing the top-left and bottom-right
coordinates, check that the center of both rectangles
are similar. If this is the case, as well as the width
and height, then they are similar.
