[Feature] Have critical section support for tests so projects don't run them in parallel

can I limit workers to 1 on a single test file? - so as to not run the test suite sequentially I have my default projects set to 3 browsers to support multi-browser tests on a single run. I have a test case that has access to a resource that cannot be shared across the 3 browsers simultaneously. In order to avoid this race condition, I had to run this test on a single worker - so all three browsers don’t run in parallel. I tried making the test file serial by test.describe.configure({ mode: 'serial' }); and test.describe.serial(title, callback) but none of them had any effect on running the test serially across the 3 browsers. I assume the playwright doesn’t support serializing the test on a project level.

`projects: [ { name: ‘chromium’, use: { …devices[‘Desktop Chrome’], }, },

{
  name: 'firefox',
  use: {
    ...devices['Desktop Firefox'],
  },
},

{
  name: 'webkit',
  use: {
    ...devices['Desktop Safari'],
  },
},`
