    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.

This option enables more stringent kabi checks. Those must
be disabled in case of a debug build, because debug builds
allow to change struct sizes.
