Based on the 1.1 doc, it has been observed that some data members in the WT_EVICT struct are currently public. This ticket aims to investigate the feasibility of converting these public data members to private to enhance encapsulation.

If this change is found to be feasible, proceed with the necessary refactoring.

For example, in a recent POC, Keith attempted to make the read_gen member private to the eviction module.

Similar changes should be explored for other data members within the WT_EVICT struct.

Acceptance Criteria:

• Review and identify public data members in the WT_EVICT struct.
• Investigate the feasibility of making these data members private.
• Implement changes if the modifications are straightforward.
