Describe the solution

Currently, there is a function that can be imported from cloudflare:mock-agent called resetMockAgent. Importantly, this function resets the interceptors. Automatically, this is used to reset things for each file. If a single test file has multiple describes that set up their own interceptors, these can leak between describes (e.g. persist: true). A solution to this is to call resetMockAgent in afterEach.

However, @cloudflare/workers-types doesn't allow for importing this function without a TS error. It would be useful to have a supported function exported from cloudflare:test to reset interceptors between tests.
