Optimize StringBuilder.Equals(ReadOnlySpan<char>) to compare by chunk#565

Walk the StringBuilder's contiguous chunks and compare each with the vectorized ReadOnlySpan.SequenceEqual, instead of indexing per char (the indexer walks the chunk list on every access). Add multi-chunk and mismatch test coverage.
