feat(lru-cache): add typed-array based LRUCache implementation

[trivikr]

Issue

Internal JS-2612

Description

Adds typed-array based LRUCache implementation.

• As per benchmarks run from lru-bench, the mnemonist/lru-cache is the most performant as it uses Typed arrays for managing pointers.
• Blog post on Implementing an efficient LRUCache in JavaScript in mnemonist.
• Documentation for LRUCache in mnemonist.
• Equivalent PR in mnemonist repo feat: add ObliviousLRUCache with delete functionality Yomguithereal/mnemonist#162

This PR would be made ready for review once it's cleared for Open Sourcing.
