Merge pull request #16861 from mppf/pragma-included-by-default
Add a pragma for modules included by default
This is a follow-up to comments in PR #16848.
It adds a pragma to indicate a module is included by default. The pragma
is used by a primitive listing symbols (to ignore default-included
symbols). It is also used by chpldoc to generate a different header for
the module. For example, look for the change in the Math module
