CNDB-12407: lazily load token in PrimaryKeyWithSource

[michaeljmarshall]

Also, add sstable overlap check to avoid certain
lookups.

What is the issue

This is a possible fix for https://github.com/riptano/cndb/issues/12407.

What does this PR fix and why was it fixed

This PR skips loading the PrimaryKey's token in the case where the sstables/memtables do not overlap.

It is implemented via a subtle change to the PrimaryKeyWithSource class that only loads the token info when the token is needed.

very nice !

we should add some unit tests to cover the new code

[michaeljmarshall]

I pushed this up to see what tests fail, if any, and to see the code coverage. I'll modify once I get those reports back.
