Chris Bracken 736d19ecbf Fix _lerpInt precision bug (flutter/engine#22089) ...

Fixes a precision bug was introduced in 5f363dc, which improved the
precision of lerpDouble when the extrema differed significantly in
magnitude.

_lerpInt doesn't have this issue since the extrema are passed as 64-bit
twos-complement values, therefore the difference will always be accurate
so long as it doesn't overflow. This reverts the _lerpInt implementation
to the original a + (b - a) * t, but adds a test to avoid a regression
if anyone is tempted to make it consistent with the others.
