test: ipa: Add test for the IPA Interface
Implement a basic test for IPA Interface using the VIMC dummy IPA module. The test implements an out-of-band feedback channel between the test and the dummy IPA module to verify the success of the IPA interactions. Test the only available operation defined by the IPA interface by receiving a confirmation code on the fifo communication channel.
