feat(ext/fetch): allow `Deno.HttpClient` to be declared with `using` (#21453)

This commit adds a method of `Symbol.dispose` to the object returned
from `Deno.createHttpClient`, so we can make use of [explicit resource
management](https://github.com/tc39/proposal-explicit-resource-management)
by declaring it with `using`.
