LUCENE-10159: Fix invalid access in sorted set dv (#389)
We introduced invalid accesses for sorted set doc values in LUCENE-9613.
However, the issue has been unnoticed because the ordinals in doc values
tests aren't complex enough to use high packed bits, and the 3 padding
bytes make these invalid accesses perfectly fine. To reproduce this
issue, we need to use at least 20 bits per value for the ordinals.

> Currently for sorted(-set) values, we always write ords using
> log2(valueCount) bits per entry. However in several cases like when the field
> is used in the index sort, or if one value is _very_common, splitting into
> blocks like we do for numerics would help.
