Remove C++ 17 workarounds for esp32. (project-chip#37778)

These fail to compile currently with an error like:

```
CMake Error at CMakeLists.txt:83 (get_target_property):
  get_target_property() called with non-existent target
  "pw_build.cpp17._public_config".

CMake Error at CMakeLists.txt:86 (set_target_properties):
  set_target_properties Can not find target to add properties to:
  pw_build.cpp17._public_config
```

The target of `_public_config` seems private so we should not
mess with it. Tested that RPC compiles locally.
