Add helper method to name parameter like $”{(keyName, value)}

[hadashiA]

Add ZLogger.Param(keyName, value) helper.
Let's give ValueTuple<string, T> special treatment.

It is for specifying the name of the parameter key for each ZLog call individually.

How to:

var id = 111;
logger.ZLogInformation($"......... {("userId",  id)} ........");

// plain text result
// #=> "......... 111 ........"

// json result
// #=> { "userId": 111, "Message": "......... 111 ........", ... }

same name of namespace and class name is......

After discussion this, I remove ZLogger.Param, and fix up instead of used (string, T)...!
