CNDB-15665 : CNDB-14861: Fix usage of PrimaryKeyWithSource in SAI

The PrimaryKeyWithSource class has been
present for two years in the code base
as an optimization for hybrid vector workloads,
which have to materialize many primary keys
in the search-then-sort query path.

However, the logic is invalid for version
aa (because we have the bug where compacted
sstables write per row, not per partition)
and it is also invalid for static columns.
This commit avoids creation of PrimaryKeyWithSource in those cases.
