The Xen events channel driver consume 72K of RAM, but may not be required in all use cases. Added a XEN_EVENTS Kconfig option so that Xen events can be gracefully disabled if not required. Updated the relevant CMakeLists.txt and Kconfig files to guard the inclusion of the Xen events driver and its source files by this option.
