Fix a corner case in SpyHashState for exact boundaries.

AbslHash allows for piecewise chunks to be streamed incrementally into hash states and requires them to hash identically to one giant stream.  The exact size window for this is an internal details `PiecewiseChunkSize`.  There was an off by one error in this code.  Add tests and fix it.
