STYLE: Alphabetize source-file entries in CMake set()/list(APPEND) commands

Pure mechanical reorder of source-file lists across 96 CMakeLists.txt
files outside Modules/ThirdParty.  No files added, removed, or renamed;
the multiset of tokens in each rewritten file is identical before and
after the sort.  Adds Utilities/Maintenance/SortCMakeSourceLists.py to
re-apply the sort and gate CI on drift via --dry-run (exits 3 when
files would change).
