[BugFix] Fix replaying AlterJob NPE Bug (backport #50100)

[mergify]

Why I'm doing:

What I'm doing:

The root cause of this bug is that the span attribute is null after restarting FE, causing NPE to be thrown when calling span. Add a default constructor to each subclass of AlterJobV2 so that span will be set to a default value after deserialization.

Fixes #50101
