tool: improve format for dumping a rowset

This changes the output for 'kudu local_replica dump rowset' to be more
human-readable. The output now looks like this:

RowIdxInBlock: 0; Base: (int32 key=0, int32 int_val=0, string string_val="HelloWorld"); Undo Mutations: [@1(DELETE)]; Redo Mutations: [];
RowIdxInBlock: 1; Base: (int32 key=1, int32 int_val=10, string string_val="HelloWorld"); Undo Mutations: [@2(DELETE)]; Redo Mutations: [];
RowIdxInBlock: 2; Base: (int32 key=2, int32 int_val=20, string string_val="HelloWorld"); Undo Mutations: [@3(DELETE)]; Redo Mutations: [];
...

rather than separately dumping each column block. Dumping individual blocks is
still possible by using the cfile dump commands.
