Subject: [PATCH] Removed unneeded includes from traits.hpp (#7509)

The `cpp/include/cudf/utilities/traits.hpp` file is parsed when building most libcudf source files (~200). This PR removes a couple unneeded header includes to help reduce the compile dependency. Only a couple files needed to be updated that relied on `traits.hpp` including these for them.
