Use stack allocation for Android data in SkScalerContext::MakeRec().
In a perfvis run on the "Boogie" test page, descriptorProc() during
detachCache() was taking .721 ms, and 20% of that was the flatten() in
MakeRec(). Changing this to a smaller stack allocation reduces the time
for descriptorProc() to .556 ms.
