LOG: [NewPM] Add deduction guide to `MFPropsModifier` to suppress warning (#96384)

Buildbot `clang-ppc64le-rhel` failed with:
```sh
error: 'MFPropsModifier' may not intend to support class template argument deduction [-Werror,-Wctad-maybe-unsupported]
note: add a deduction guide to suppress this warning
```
after #94854. This PR adds deduction guide explicitly to suppress
warning.
