mm: make MEMFD_CREATE into a selectable config option
The memfd_create() syscall, enabled by CONFIG_MEMFD_CREATE, is useful on
its own even when not required by CONFIG_TMPFS or CONFIG_HUGETLBFS.
Split it into its own proper bool option that can be enabled by users.
Move that option into mm/ where the code itself also lies. Also add
"select" statements to CONFIG_TMPFS and CONFIG_HUGETLBFS so they
automatically enable CONFIG_MEMFD_CREATE as before.
