Adding MandatoryExtensionsForIncognitoNavigation to Android Desktop

This CL adds the MandatoryExtensionsForIncognitoNavigation policy
to Android desktop.

I manually tested this CL by adding this policy with an extension
and made sure that I could not navigate if the extension was not
there - as well as that it passed otherwise. So seems to be doing
what is expected.

There is a one browsertest for this located in

"../chrome/browser/enterprise/incognito/incognito_navigation_throttle_browsertest.cc",

however - this will require the entire browsertest framework to be
present (which it is not). As such that test was not re-enabled.
I filed bug (416755147) for tracking to do this later.
