kernel/kexec_core: move kexec_core sysctls into its own file
This move the kernel/kexec_core.c respective sysctls to its own file.
kernel/sysctl.c has grown to an insane mess, We move sysctls to places
where features actually belong to improve the readability and reduce
merge conflicts. At the same time, the proc-sysctl maintainers can easily
care about the core logic other than the sysctl knobs added for some feature.
We already moved all filesystem sysctls out. This patch is part of the effort
to move kexec related sysctls out.
