Use MGLRU's debugfs interface to do access tracking instead of page_idle. The logic to use the page_idle bitmap is left in, as it is useful for kernels that do not have MGLRU built in. When MGLRU is enabled, page_idle will report pages as still idle even after being accessed, as MGLRU doesn't necessarily clear the Idle folio flag when accessing an idle page, so the test will not attempt to use page_idle if MGLRU is enabled but otherwise not usable. Aging pages with MGLRU is much faster than marking pages as idle with page_idle.
