TracedProto: Fix MSVC compilation

MSVC doesn't take too kindly to having multiple member functions with
the same signature, despite all but one not having a valid return type.
They should have been ignored due to SFINAE, but they aren't (more details here:
https://developercommunity.visualstudio.com/t/c-compiler-fails-sfinae-error-c2535/671364)

Switch the implementation of the TracedProtoWriter from multiple
SFINAE implementations of the same functions to partial specialisations
of a nested struct.
