Split the HAVE_BPF_JIT into two for distinguishing cBPF and eBPF JITs.
Current cBPF ones:
# git grep -n HAVE_CBPF_JIT arch/
arch/arm/Kconfig:44: select HAVE_CBPF_JIT
arch/mips/Kconfig:18: select HAVE_CBPF_JIT if !CPU_MICROMIPS
arch/powerpc/Kconfig:129: select HAVE_CBPF_JIT
arch/sparc/Kconfig:35: select HAVE_CBPF_JIT
Current eBPF ones:
# git grep -n HAVE_EBPF_JIT arch/
arch/arm64/Kconfig:61: select HAVE_EBPF_JIT
arch/s390/Kconfig:126: select HAVE_EBPF_JIT if PACK_STACK &&
HAVE_MARCH_Z196_FEATURES
arch/x86/Kconfig:94: select HAVE_EBPF_JIT if X86_64
Later code also needs this facility to check for eBPF JITs.
