More benchmarks for the `node:test` module.

The benchmark/test_runner folder currently contains benchmarks for it and describe functions. I suggest we expand these benchmarks to cover additional test runner features, including mocks, coverage, and various test modes.

Here are the functions that (IMO) should be benchmarked:

Basic Testing

These tests should run with a custom reporter without any special logic to make the tests as accurate as possible.

• test
  • Create a test (#56479)
  • Create a test when it's not running due to only
  • Add a subtest
  • Skip a test
    • Via skip: true
    • Via t.skip()
    • Via t.skip(...)
  • TODO tests
    • Via todo: true
    • Via t.todo()
    • Via t.todo(...)

Hooks

• beforeEach
• afterEach
• before
• after

Reporters (#55757)

• dot
• junit
• spec
• tap
• lcov

Mocking

• mock.fn (#55771)
• mock.timers for each API, and each sub-function
• mock.module

Snapshots

• snapshot.setDefaultSnapshotSerializers(serializers)
• snapshot.setResolveSnapshotPath(fn)
• t.assert.snapshot

Coverage

Use --expose-internals to exclusively test the coverage part

• Basic
• Excluding files
• Including files
• With source maps

从 benchmark/test_runner 开始，检查 it、describe 以及已完成的 test-runner 功能对应的现有基准测试。为尚未勾选的 mock.timers、mock.module、snapshot 和 coverage 用例添加基准测试，并为 coverage 使用自定义 reporter 和 --expose-internals。剩余的检查清单项目都在不使用特殊基准测试逻辑的情况下得到覆盖，即表示完成。
