[AMD][Triton] Fix C++ compilation errors in generated launcher code (#1212)

Summary:
Pull Request resolved: #1212

The AMD Triton backend generates C++ launcher code at runtime that
failed to compile with clang-20 in strict C++ mode due to:
- Enum type mismatch: HIP_SUCCESS vs hipSuccess
- Implicit int-to-enum assignment for hipLaunchAttributeID
- Narrowing int-to-unsigned-int conversions in HIP_LAUNCH_CONFIG initializer
