detect fixed overflow in drawPoints

This particular test this is addressing is:

1. very large device (>32K in a test case)
2. drawPoints has special (fast) case where it converts all of the pts (rects) into fixed point
3. overflows fixed -- assert

Paths already don't draw into a device this large (they are limited by 32K I think, smaller if aa)
The (theoretical) solution for paths is to tile the draw itself. Perhaps that approach could be
applied everywhere in bitmapdevice...

This older issue sums up this idea: https://bugs.chromium.org/p/skia/issues/detail?id=2122
Will look into this general solution in a separate CL/effort.
