Use numpy directly instead of numpy_fast for clip and interp

Replaced occurrences of `openpilot.common.numpy_fast` with direct imports from `numpy` across multiple files. This simplifies dependencies and ensures consistency with standard Python library usage. Adjusted tests to mock `numpy` functions accordingly.
