refactor(optimizer): remove strtotime from direct wrapper optimization

- Removed strtotime from the list of functions that use direct PHPX wrappers
- Updated test case to verify only supported datetime calls use direct wrappers
- Modified strtotime test to include absolute, relative, epoch 0 and invalid dates
- Added timezone setting and additional test cases for relative date handling
- Updated expected test output to reflect new strtotime behavior
- Adjusted assertions to check for correct persistent function calls
