Make tempTouchState a local variable
Currently, mTempTouchState is a class variable, and it is confusing when
it is being modified in functions such as findTouchedWindowAt.
This variable is only used inside findTouchedWindowTargets, so convert
it to a local variable. This will make it easier to keep track of its
contents.
