LOG: [clang-tidy] Restore test parameter operator<< function (NFC)

Clang erroneously flagged the function as "unused", but it is most
definitely used by gtest to pretty print the parameter value when
a test fails.

Make the pretty printing function a friend function in the parameter
class similar to other clang unit tests.
