Add VercelKVCache to support caching with @vercel/kv

• I searched existing ideas and did not find a similar one
• I added a very descriptive title
• I've clearly described the feature request and motivation for it

Feature request

Currently, the project provides caching functionality for Upstash Redis through the UpstashRedisCache class. Given that Vercel KV shares the same foundational technology as Upstash Redis and there is already an implementation of VercelKVStore, it is both feasible and beneficial to implement a VercelKVCache class.

Motivation

For developers relying on Vercel’s infrastructure, there is no native support for caching with @vercel/kv, despite its similarity to Upstash Redis.
