[Nav Experiment] Make WebStateImplTest parameterized.

This way both legacy and WK based navigation manager implementations are
tested on trybots.

Fixed incorrect test setup in ShowAndClearInterstitialWithNoCommittedItems.
Disabled ShowAndClearInterstitialWithCommittedItem and
ShowAndClearInterstitialWithoutChangingSslStatus because they require
mocking out navigation state, which is not possible now.

[Nav Experiment] Parameterize crw_web_controller_unittest.mm.

This is so that both LegacyNavigationManagerImpl and
WKBasedNavigationManagerImpl can be tested on trybots.

Also fixed broken test setup for
ScriptExecutionTest.UserScriptOnAppSpecificPage and
CRWWebControllerTest.AbortNativeUrlNavigation.
