Some of the current timeout error messages are confusing, because they do not suggest that the issue is most likely a slow test. This PR updates timeout messages as follows:
- Test timeout of 30000ms exceeded.
- Test timeout of 30000ms exceeded while setting up "browser".
- Test timeout of 30000ms exceeded while tearing down "context".
- Test timeout of 30000ms exceeded while setting up "playwright configuration".
- Test timeout of 30000ms exceeded while running "beforeEach" hook.
- Test timeout of 30000ms exceeded while running "afterEach" hook.
- "beforeAll" hook timeout of 30000ms exceeded.
- "afterAll" hook timeout of 30000ms exceeded.
- Worker teardown timeout of 30000ms exceeded.
- "skip" modifier timeout of 30000ms exceeded.
- Fixture "myCustomFixture" timeout of 5000ms exceeded.
- Always show a fixture that was running during timeout.
- Give custom titles to built-in fixtures.
- Specify setup/teardown fixture phase in the message.
- Split connect vs launch browser fixtures for better naming.
Example timeout message:
```log
Timeout of 2000ms exceeded while running fixture "built-in playwright configuration" teardown.
```
By default, fixtures share timeout with the test they are instantiated for.
However, for more heavy fixtures, especially worker-scoped ones, it makes
sense to have a separate timeout.
This introduces `{ timeout: number }` option to the list of fixture options
that opts the fixture into a dedicated timeout rather than sharing it
with the test.
