Set set-force-adoptable to run AdoptableHostTest correctly

AdoptableHostTest requires PROP_ADOPTABLE system property to be set for
all the tests to run. All the tests in AdoptableHostTest need to run in
the same boot time except for the testFeatureConsistency test. It
checks if the value of PROP_ADOPTABLE at boot time is consistent with
the current value. Therefore, it needs reboot.

Separated the tests that need to run in the same boot sequence and the
one that needs reboot by creating a new test class.
