Stubbing cpuinfo for Apple ARM plateform. Handling Apple M1 correctly and adding support for SSE2NEON. Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Comments clean up and refactor some comments and documentations Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Added something in the documentation for Rosetta and small change in cmake Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Fixing the build under Rosetta and fixing issue in the MacOS CI.
