Feature lru cache wrapper 2 (#9511)
* Add Wrapper to LRU Cache to handle Invalid Parameters #9461

* Regenerate BUILD.bazel and simplify tests using lru.Cache

* Fix: fuzz_exports.go build error

* Fix: block_fuzz.go

* Revert lru.Cache interface

* Remove redundant err check in pending_attestations_queue_test.go

* Add tests for lru wrapper

* Use lru package in prysm/shared instead of lruwrpr

* Fix: goimports

* Fix: BUILD.bazel
