James Houghton d166453ebd KVM: selftests: access_tracking_perf_test: Use MGLRU for access tracking
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.
