Constructs new error condition.

1) Default constructor. Initializes the error condition with generic category and error code ​0​.
2) Initializes the error condition with error code val and error category cat.
3) Initializes the error condition with enum e. Effectively calls make_error_condition that is only found by argument-dependent lookup for e. This overload participates in overload resolution only if std::is_error_condition_enum<ErrorConditionEnum>::value is true.
4,5) Implicitly defined copy constructor and move constructor. Initializes the error condition with the contents of the other.


other - another error condition to initialize with
val - error code
cat - error category
e - error condition enum
