Fix clang-tidy misc-unused-params warnings (#35433)

# Fix clang-tidy `misc-unused-params` warnings

## Summary

This PR applies fixes for clang-tidy's `misc-unused-params` check, which
identifies and removes unused function parameters. The changes ensure
that function signatures match their actual usage, improving code
clarity and maintainability.

## Changes Made

### 1. Removed Unused Variables
- **`ttnn/cpp/ttnn/operations/data_movement/scatter/tosa_scatter.cpp`**:
Removed unused variable `K` (line 132)
-
**`ttnn/cpp/ttnn/operations/data_movement/pad/device/pad_rm_reader_writer_multi_core_program_factory.cpp`**:
Removed unused variable `nchannel` (line 196)
-
**`ttnn/cpp/ttnn/operations/eltwise/unary/device/unary_device_operation.cpp`**:
Removed unused variable `arch` (line 80)

### 2. Fixed Function Signature Mismatches

#### Slice Operations
-
**`ttnn/cpp/ttnn/operations/data_movement/slice/device/slice_program_factory_tile.cpp`**:
- Removed `num_cores` argument from `set_slice_runtime_args_tile()`
calls (2 locations)
- Function signature was updated by clang-tidy but call sites weren't
updated
  
-
**`ttnn/cpp/ttnn/operations/data_movement/slice/device/slice_program_factory_tile_tensor_args.cpp`**:
- Removed `num_cores` argument from
`set_slice_runtime_args_tensor_args()` calls (2 locations)
- Function signature was updated by clang-tidy but call sites weren't
updated

#### Grid Sample Operations
-
**`ttnn/cpp/ttnn/operations/pool/grid_sample/grid_sample_prepare_grid.cpp`**:
- Removed unused `output_dtype` parameter from
`create_host_buffer_for_grid_preprocessing()` call
- The function signature was updated by clang-tidy but the call site
wasn't updated

### 3. Fixed Template Function Calls
- **`ttnn/cpp/ttnn/operations/eltwise/unary/unary_nanobind.cpp`**: 
- Updated bind function calls to remove second argument (operation
object) and explicitly specify template parameters using `decltype`
- Fixed functions: `bind_softplus`, `bind_sigmoid_accurate`,
`bind_sigmoid_mode_appx`, `bind_unary_chain`, `bind_identity`
- These functions use the operation directly from the namespace, so the
parameter was removed by clang-tidy

### 4. Updated Test Code
- **`tests/ttnn/unit_tests/gtests/test_launch_operation.cpp`**: 
  - Updated test structs to match expected method signatures:
- Added `const std::vector<Tensor>& input_tensors` parameter to
`compute_output_specs()` methods
- Added `const std::vector<Tensor>& input_tensors` parameter to
`create_output_tensors()` methods
- Added `const ttnn::MeshCoordinateRangeSet& mesh_coordinate_range_set`
parameter to `create_mesh_workload()` method
- These changes ensure test mocks match the actual operation interface
requirements

## Testing

- ✅ Build passes with `./build_metal.sh --debug --build-all`
- ✅ All clang-tidy `misc-unused-params` warnings resolved
- ✅ No functional changes - only signature updates to match actual usage

## Notes

- The clang-tidy tool automatically removed unused parameters from
function signatures, but some call sites needed manual updates
- All changes maintain backward compatibility at the API level - only
internal implementation details were modified
- Test code was updated to ensure test mocks correctly implement the
expected interfaces
