[bun:test] Implement `beforeEachFile` and `afterEachFile` hooks

[Jarred-Sumner]

What does this PR do?

This adds support for adding a function to call before each test file runs and after each test file runs:

In a preload script:

import {beforeEachFile, afterEachFile} from 'bun:test';

beforeEachFile(() => {
  resetDatabase();
});

In a test:

import {test, expect} from 'bun:test';

test("signup user in database", async () => {
  doSomething();
});

When switching tobun:test from vitest or jest, there currently is no equivalent to setupFiles. This adds an alternative .

How did you verify your code works?

WIP. Needs automated tests.

This is still needed to be able to port many test suites.
