Now that the v1 mount code is split into separate functions, move them
to kernel/cgroup/cgroup-v1.c along with the mount option handling
code. As this puts all v1-only kernfs_syscall_ops in cgroup-v1.c,
move cgroup1_kf_syscall_ops to cgroup-v1.c too.

Currently, cgroup_kf_syscall_ops is shared by v1 and v2 and the
specific methods test the version and take different actions. Split
out v1 functions and put them in cgroup1_kf_syscall_ops and remove the
now unnecessary explicit branches in specific methods.

cgroup.c is getting too unwieldy. Let's move out cgroup v1 specific
code along with the debug controller into kernel/cgroup/cgroup-v1.c.
v2: cgroup_mutex and css_set_lock made available in cgroup-internal.h
regardless of CONFIG_PROVE_RCU.
