Refactor Cache.CacheStats with Builder pattern

[pado0]

Description

This PR refactors the Cache.CacheStats class to use the Builder pattern instead of relying on multiple constructors.

By adopting the Builder pattern, it becomes easier to evolve the stats API, add new metrics, and maintain backward compatibility without forcing disruptive constructor changes.

Based on the related issue:

1. Added a Builder and deprecated the existing constructors.
2. Replaced usages of constructors in code and tests with the new Builder.

There are multiple stats-related classes that need similar refactoring, and we are addressing them in priority order. This PR covers Cache.CacheStats as part of that effort.
