Move tools/testing/selftests/mm/gup_test.c to tools/mm/gup_bench.c. This is the first step in separating its benchmarking and functional testing components. Later patches will make this a purely benchmarking tool and introduce a new functional selftest under selftests/mm. Include hugepage_settings.h directly instead of vm_util.h and use getpagesize() instead of psize(). Adjust the Makefiles in both locations and add gup_bench to tools/mm/.gitignore. Remove the gup_test invocations from run_vmtests.sh and update MAINTAINERS. Also remove the gup_test reference from Documentation/core-api/pin_user_pages.rst. The selftest added later in the series is standalone and does not need per command documentation here.
