Removal of MicroProfile support not documented on EAP 7.4 Migration Guide

The removal of MicroProfile from EAP 7.4, no matter being a tech preview feature of EAP 7.3, should be documented in the EAP 7.4 Migration Guide, due to standard EAP 7.3 server configurations failing to boot on EAP 7.4.

A new section should be added to the Server Configuration Changes chapter, which should guide users on the necessary changes to be done on server configurations, i.e. remove the unsupported extensions and subsystem configurations. The section "2.5. Review The List of Deprecated and Unsupported Features" could also be improved to refer the MicroProfile support removal.
