kernel: clean-up build-configurable kernel config symbols

Don't explicitely disable options in target/linux/generic/config-* if
they are already controlled in config/Config-kernel.in.
Add a bunch of new symbols  and prepare defaults for using only unified
hierarchy (ie. cgroup2). Update symbol dependencies while at it
