Making add and clear CPIF apis as TestApis

Making addCrossProfileIntentFilter and clearCrossProfileIntentFilters as
TestApis so that we can write CTS device side test cases to emulate
behaviour used by 3P apps or profile owners. This is to ensure that no
malicious user can add/remove filters by following access control rules.
