[PATCH bpf-next v4 1/4] arm64: move AARCH64_BREAK_FAULT into insn-def.h

[Hou Tao]

If CONFIG_ARM64_LSE_ATOMICS is off, encoders for LSE-related instructions
can return AARCH64_BREAK_FAULT directly in insn.h. In order to access
AARCH64_BREAK_FAULT in insn.h, we can not include debug-monitors.h in
insn.h, because debug-monitors.h has already depends on insn.h, so just
move AARCH64_BREAK_FAULT into insn-def.h.

It will be used by the following patch to eliminate unnecessary LSE-related
encoders when CONFIG_ARM64_LSE_ATOMICS is off.
