chore!: remove pub visibility on OVERFLOW_LRU_CAPACITY and STATE_LRU_CAPACITY_NON_ZERO (#8234)

- Renames `OVERFLOW_LRU_CAPACITY` to `OVERFLOW_LRU_CAPACITY_NON_ZERO` to follow naming convention of `STATE_LRU_CAPACITY_NON_ZERO`
- Makes  `OVERFLOW_LRU_CAPACITY_NON_ZERO` and `STATE_LRU_CAPACITY_NON_ZERO` private since they are only used in this module
- Moves `STATE_LRU_CAPACITY` into test module since it is only used for tests
