[PATCH v6 3/6] tools/lib/mm: move hugepage_settings out of selftests

Move hugepage_settings.[ch] from tools/testing/selftests/mm/ to tools/lib/mm/ so the THP and HugeTLB helpers can be shared more easily between selftests and other tools. Keep the helpers exposed to mm selftests through vm_util.h where possible, and use direct <mm/hugepage_settings.h> includes for files that do not include vm_util.h. Adjust the selftests/mm build to compile the moved implementation from its new location. Remove the remaining kselftest dependency from hugepage_settings.c. Replace ksft_perror() with a new print_file_error() helper and ksft_print_msg() with printf(). Prefix both with a # to keep them TAP compatible.
