Remove the WFLY-14219 comments from the module.xml files

As part of WFLY-14219 we added a comment about it to a bunch of module.xml files. Over time those comments are starting to lose their relationship to the other module.xml content and aren't providing useful information any more. So let's remove them.

Comment looks like:

<!--WFLY-14219 Remove deprecated <module name="javax.api"/> -->
