We move the code for creating the temporary directory to sage.misc.temporary_file, removing the dependency on sage.misc.misc and sage.misc.lazy_string.

This is preparation for #29941, allowing us to keep sage.misc.misc out of sagemath-objects and sagemath-repl; sage.misc.temporary_file goes into sagemath-environment.
