Subject: fix(ext/kv): KvU64#valueOf and KvU64 inspect (#18656)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`new Deno.KvU64(1n) + 2n == 3n` is now true.

`new Deno.KvU64(1n)` is now inspected as `[Deno.KvU64: 1n]`
(`Object(1n)` is inspected as `[BigInt: 1n]`).
