bpf: split HAVE_BPF_JIT into cBPF and eBPF variant
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.
