Pass cache stats to TBE only when using LRU

[sryap]

Summary: This diff introduces a condition to pass local_uvm_cache_stats to TBE only when using the LRU policy.

When local_uvm_cache_stats is passed to TBE, it utilizes the cache unique conflict misses information to determine whether to load data entirely or partially from cache, UVM, or HBM. If this information is inaccurate, TBE may produce an incorrect output. Since the unique conflict misses stat is only collected during the cache lookup only when the LRU cache eviction policy is used, local_uvm_cache_stats should not be passed to TBE when other cache eviction policies are used.
