Introducing CAP-0065: Optimizing Soroban with Reusable Module Cache

CAP-0065 proposes a persistent, reusable module cache to maintain live WASM modules across ledgers, reducing parsing and validation costs. This aligns with efforts to lower network costs and enhance scalability. The proposal builds on CAP-0062 and CAP-0063 to avoid resetting cache after each transaction, making the caching process more efficient.
