redhat: kABI: add missing RH_KABI_SIZE_ALIGN_CHECKS Kconfig option
When the kABI macros were copied from the RHEL kernel to ARK, the
RH_KABI_SIZE_ALIGN_CHECKS config option was dropped. Without it, the
size checks included in some of the kABI macros can't be enabled.
Add the KABI_SIZE_ALIGN_CHECKS config option, enable it on RHEL
configs, and disable it for debug, rt, and zfcpdump kernels.
