What does the present simple mean? Why is it used?

It is used here to indicate a state. Remember that the present continuous cannot be used with some verbs (stative verbs and verbs that indicate a quick/instantaneous action). In the above context, come means stand or be (present). Also note that coming cannot work in that sentence, because it would indicate that the person is elsewhere and is on their way to that place.

Is it like the ones below?
a. I now declare this meeting open.

That's a quick/instant action verb.

b. I take full responsibility for losing the election and I hereby resign from the Central Committee.

Here, take is a stative verb (meaning bear), while resign is a quick/instantaneous one.

c. I enclose herewith a check of 50 dollars.

Again, "enclose" is a quick/instantaneous verb.

Having said all that, note that with some verbs it is possible to use either tense. For example, it would not be unusual to come across "I am enclosing herewith a check for $50", or "I am resigning from the Central Committee", with some justification. This is because "enclosing" and "resigning" can be processes of some duration (not always quick or instantaneous).

The answer is: no, it isn't. And neither is enclose in example c.
