logging/nxscope: add an option to disable lock in channels put interfaces

Browse Source 
With this option enabled the user can speed up adding a large amount of data to the stream buffer
by minimizing the usage of the nxscope lock interface:

  nxscope_lock(&nxs->nxs);
  nxscope_put_vfloat(&nxs, 0, data0, 1);
  nxscope_put_vfloat(&nxs, 1, data1, 1);
  nxscope_put_vfloat(&nxs, 2, data2, 1);
  nxscope_put_vfloat(&nxs, 3, data3, 1);
  nxscope_unlock(&nxs->nxs);

This option disables lock in channels put interfaces.
In that case, the user is responsible for ensuring
thread-safe operations with nxscope_lock/nxscope_unlock functions.
