Switch TF to C++17 standard.

Remove old C++17 config flags, we'll build with C++17 by default.

Force nvcc to use C++17 dialect by changing the wrapper script to include the forcing flag.

Fix some TFLite static string constant that needs to be constexpr now.

Note: We probably need a little bit more cleanup to remove duplicate RBE configs. But let's leave this for a separate change.

All changes here (and in previous commits for the C++17 conversion) tested on https://godbolt.org/z/1PebET71j. Probably not relevant if looking just at this commit alone though.
