kFill_PathAsRect is added for those non-closed paths in SkPath::asRect. this
kind path draws the same as its bounds only if is filled. When it is filled, the
painter will close the path implicitly during rendering. Otherwise, If the path
is closed, it can always draws the same as its bounds(a rect) even it is
stroked, we return kStroke_PathAsRect for closed path.

As a result:
For kFill_PathAsRect paths, the updated isRect() return true, parameter
'isClosed' is false.
For kStroke_PathAsRect paths, the updated isRect() return true, parameter
'isClosed' is true.

So I exchanged kFill_PathAsRect and kStroke_PathAsRect to make it align to the
design logic.
