Add default_breakpoint_from_pc

This patch adds the default implementation of gdbarch breakpoint_from_pc,
which is,

const gdb_byte *
default_breakpoint_from_pc (struct gdbarch *gdbarch, CORE_ADDR *pcptr,
                           int *lenptr)
{
  int kind = gdbarch_breakpoint_kind_from_pc (gdbarch, pcptr);

  return gdbarch_sw_breakpoint_from_kind (gdbarch, kind, lenptr);
}

so gdbarch can only defines sw_breakpoint_from_kind and
breakpoint_kind_from_pc.
