  [PR49761] Fix variadic arg handling in matcher

Mishandling of variadic arguments in a function call caused a crash
(runtime assert fail) in bugprone-infinite-loop tidy checker.  Fix
is to limit argument matching to the lesser of the number of variadic
params in the prototype or the number of actual args in the call.
