Review comment:
       We either need to add
   ```
   #if CONFIG_TLS_TASK_NELEM > 0
   #  if CONFIG_TLS_TASK_NELEM > 64
   #    error Too many task TLS elements
   #  elif CONFIG_TLS_TASK_NELEM > 32
        typedef uint64_t tls_task_ndxset_t;
   #  elif CONFIG_TLS_TASK_NELEM > 16
        typedef uint32_t tls_task_ndxset_t;
   #  elif CONFIG_TLS_TASK_NELEM > 8
        typedef uint16_t tls_task_ndxset_t;
   #  else
        typedef uint8_t tls_task_ndxset_t;
   # endif
   ```
   and use `tls_task_ndxset_t` here or just use `uint64_t` for simplicity. 
Since this is globally allocated, then we can go with `uint64_t`.
