This is a drop-in replacement to add metrics to an LRU cache.

Usage:

-   txLookupCache *lru.Cache[common.Hash, txLookup]
+   txLookupCache *lru.MeteredCache[common.Hash, txLookup]
-   txLookupCache:      lru.NewCache[common.Hash, txLookup](txLookupCacheLimit),
+   txLookupCache:      lru.NewMeteredCache[common.Hash, txLookup](txLookupCacheLimit, "txLookupCache"),
