What's this PR

https://github.com/TanStack/table/issues/5363

The above issue reported that getValues returns stale cached values after changing accessor functions.

This PR fixes it.

8cd8449: add unit tests f66f4e6: accessor functions are also held as cache, and it determines whether the cached data are fresh or stale.
