Support passing a AbortSignal to cache.match

Because of how Cloudflare is tracing async executions (https://zuplo.com/blog/2022/03/04/the-script-will-never-generate-a-response), when implementing concurrent logic with `Promise.race` or similar, it's prefered to use a signal to abort any underlying fetch.

For example in my case I want to read from multiple caches in parallel, and one of them is the `caches.default`. But in theory the script might respond before all the caches finished responding.

It'd be great if we could pass a `AbortSignal` to `cache.match`:

```ts
const abort = new AbortController();
const response = await cache.match(request, { signal: abort.signal });
```
