[Rd] R_tryEval not properly documented in 'Writing R Extensions' (PR#9524)

Considering the lack of embedding documentation until relatively
recently, the fact that the function appeared in Rinternals and the
Embedding test cases makes it more part of the API that its appearance
in any documentation since anyone embedding would have to base their
work on those test cases.
In any case, my second claim---that the function is used heavily by
projects under the official R umbrella as well as outside of
it---still stands and should probably serve as sufficient cause to
nominate R_tryEval for the public API.
