ovr_Achievements_AddCount Function

Add 'count' to the achievement with the given name. This must be a COUNT achievement. The largest number that is supported by this method is the max value of a signed 64-bit integer. If the number is larger than that, it is clamped to that max value before being passed to the servers.

A message with type ovrMessage_Achievements_AddCount will be generated in response.

First call ovr_Message_IsError() to check if an error occurred.

If no error occurred, the message will contain a payload of type ovrAchievementUpdateHandle. Extract the payload from the message handle with ovr_Message_GetAchievementUpdate().
