fix very large clipped path limit
Mozilla notes that clipped paths conservatively triple
the reserved space for a path edge list, potentially
overflowing an int if the point count is 2^31/3 or
larger, making maxEdgeCount negative if maxEdgeCount
is an int.
By making maxEdgeCount size_t, the multiply stays in
range. A couple of lines down, makeArrayDefault is going
to trigger an SkASSERT_RELEASE because the record size
times the point count exceeds the allowable limit.
