mm, slub: remove slub_memcg_sysfs boot param and CONFIG_SLUB_MEMCG_SYSFS_ON
The boot param and config determine the value of memcg_sysfs_enabled, which is unused since commit 10befea91b61 ("mm: memcg/slab: use a single set of kmem_caches for all allocations") as there are no per-memcg kmem caches anymore.

- SLUB creates a directory under /sys/kernel/slab for each
- allocation cache to host info and debug files. If memory
- cgroup is enabled, each cache can have per memory cgroup
- caches. SLUB can create the same sysfs directories for these
- caches under /sys/kernel/slab/CACHE/cgroup but it can lead
- to a very high number of debug files being created. This is
- controlled by slub_memcg_sysfs boot parameter and this
- config option determines the parameter's default value.
