We would like to make the cpu_exec_halt method mandatory so we can remove the runtime check and fallback handling. In preparation for that, make all the targets which don't need special handling in their cpu_exec_halt set it to their cpu_has_work implementation instead of leaving it unset. (This is every target except for arm and i386.) In the riscv case this requires us to make the function not be local to the source file it's defined in.
