6ac852f3 - Move Float16 print tests to their own file and test exhaustively (#72859)

Move Float16 print tests to their own file and test exhaustively (#72859) We can easily test all 2**16 values, so let's do it. Also now _Float16 is properly supported in clang, so we can pass arguments to CPP that way, which lets us get snan right on more platforms.
