ref(v7): Deprecate addRequestDataToTransaction (#11368)

This is not used/needed anymore in v8, and also is coupled to
transactions.

Not sure if we need to add this to migration docs, as this is from utils
and was more internally used...? (Also, I guess if so we need to add it
to migration docs in a separate PR on develop...?)
