qcacmn: Modify trace related APIs to support dynamic configuration in WIN

New iwpriv commands are implemented in WIN to support dynamic configuration
of verbose level for each of the module IDs.

Add following changes in trace module to support above requirement -

1. Make qdf_get_pidx and qdf_set_pidx common to WIN and MCL
2. Export g_qdf_category_name to be accessible in WIN driver
3. Add macros to derive upper and lower 16-bits from a 32-bit value
   combining module and trace level information used for dynamic trace
   level configuration per module
4. Address trace level NONE case during registration to set the correct
   mask
