doc: fix doxygen for timer API

Now that some of the symbols in the timer lib are versioned, the
Doxygen documentation that is generated is incorrect.  Group all
versioned symbols, listing the generic name first, and remove comments
for older versions of symbols.

Fixes: c0749f7096c7 ("timer: allow management in shared memory")
