[Feature]: Pass destroyAfterEach in the config

[chabb]

🚀 Feature Proposal

Is it possible to pass destroyAfterEach in the configuration file ?
It does not seem to be the case without explicitly doing:

getTestBed().initTestEnvironment(BrowserDynamicTestingModule, platformBrowserDynamicTesting(), {
  teardown: {
    destroyAfterEach: true, // Angular recommends this, but it may break existing tests
  },
});

Motivation

Our tests fail on angular12, if this flag is set to false; and it's false by default on angular 12
