[Feature]: Provide an option to disable all timeouts in debug mode

[vitalets]

🚀 Feature Request

Provide an option to disable all timeouts in debug mode. Otherwise, if there are pending promises (e.g. waitFor*), browser closes automatically.

Example

Imagine the following test:

 test('Check title', async ({ page }) => {
    const promise = page.waitForRequest(/Browsers/, { timeout: 5000 });
    await page.goto('https://playwright.dev');
    await promise;
});

When I run it as npx playwright test - everything ok.
When I run it as npx playwright test --debug - browser closes after 5 seconds. So I actually can't debug my test.

Motivation

I want to be able to debug my tests without any timeouts.
