Added new test cases for `Float16.toString()` within `BasicFloat16ArithTests`. These tests cover special values, boundary values, the transition point between normal and subnormal numbers, and the threshold for switching between standard and scientific notation; they also verify the consistency of the output between the static and instance versions of `toString()`.
