Memory allocation improvement for `decode_libsvm` (#15803) 



* Memory allocation improvement for `decode_libsvm`

This fix is an improvement to 14330. Previously string split
was handled through `str_util::Split`, which may incur unnecessary
memory allocations. This fix uses StringPiece instead.

See comment 14330 for reference.
