erts: Remove ERTS_SMP and USE_THREAD defines

This refactor was done using the unifdef tool like this:
    for file in $(find erts/ -name *.[ch]); do unifdef -t -f defile -o $file $file; done

where defile contained:
    #define ERTS_SMP 1
    #define USE_THREADS 1
    #define DDLL_SMP 1
    #define ERTS_HAVE_SMP_EMU 1
    #define SMP 1
    #define ERL_BITS_REENTRANT 1
    #define ERTS_USE_ASYNC_READY_Q 1
    #define FDBLOCK 1
    #undef ERTS_POLL_NEED_ASYNC_INTERRUPT_SUPPORT
    #define ERTS_POLL_ASYNC_INTERRUPT_SUPPORT 0
    #define ERTS_POLL_USE_WAKEUP_PIPE 1
    #define ERTS_POLL_USE_UPDATE_REQUESTS_QUEUE 1
    #undef ERTS_HAVE_PLAIN_EMU
    #undef ERTS_SIGNAL_STATE
