[ESW] Expand some chrome.webNavigation tests to SWs (15-17 / 23)

This CL expands following webNavigation apitests to workers:
  - WebNavigationApiTestWithContextType.RequestOpenTab
  - WebNavigationApiTestWithContextType.ServerRedirect
  - WebNavigationApiTestWithContextType.ServerRedirectSingleProcess

This CL picks (semi-randomly) 3 tests from chrome.webNavigation apitests.

This is similar to other WebNaviationApiTest's expansion to workers,
e.g. crrev.com/c/2844543.

Bug: 1205340
Test: None, internal test only change.
