test: libipa: Add Vector class test

Browse source 
Add a unit test to exercize the API of the ipa::Vector class.

The test binary being called 'vector', implicit includes cause the
binary to be picked by '#include <vector>', causing builds to fail. Set
implicit_include_directories to false to avoid this, as done in commit
6cd8491258 ("test: Don't add current build directory to include
path").
