Remove unused method and constant in View

Turns out when you have IJ set up a lot of things become
more easy to spot.

sLayoutParamsAlwaysChanged was added in ag/818432, but then
not removed in ag/825933 when the feature was pulled.

transformRect was added in ag/173465 but never actually used.

Test: make -j
