SkVertices: Fix out-of-memory errors in deserialization
It was easy to construct a buffer that indicated enormous amounts of
memory had to be allocated. An easy guard is to bail out if the buffer
can't possibly fill those buffers.
Simplify the code a bit: Four years ago (well past the earliest
supported SKP version), we stopped writing out triangle fan data (by
converting to tri-lists at construction time). Remove the
deserialization support, which makes the code easier to follow.
