Fix issue #21936: Add missing clip and clip_ functions to paddle frontend

- Added clip function to ivy/functional/frontends/paddle/math.py
- Added clip_ inplace function to ivy/functional/frontends/paddle/math.py
- Added comprehensive tests for both functions in test_paddle/test_math.py
- Functions follow established patterns with proper decorators and error handling
- clip_ uses ivy.inplace_update pattern consistent with other inplace operations
