Fix failing mainline build on Arm64 linux (#27101)

### Description
`sconv.h` was renamed to `sconv_nchwc_kernel_neon.h` in #26688 but the
reference to the old name was still in a new file added at around the
same time in #26838.
The CI doesn't include building for this configuration yet - it will be
added after the 1.24 release.



### Motivation and Context
Fixes failing mainline build on Arm64 linux when
`--enable_arm_neon_nchwc` is supplied.


### Testing
This now passes on Arm64 linux
`./build.sh --config Release --build_shared_lib --parallel
--compile_no_warning_as_error --skip_submodule_sync --skip_tests
--enable_pybind --build_wheel --enable_arm_neon_nchwc`
