docs(prt): update structure of blocks section for prp/oc (#2005)

The new dimensions and tracktimes/releasetimes blocks added to output control and particle release packages, respectively, were not mentioned in the mf6io guide. Also fix inconsistent descriptions of the release timing mechanism in PRP DFN.

* fix #2002
* fix #2003
* fix #2004

 For the PRINT and SAVE options, there is no option to specify individual layers.  Whenever the budget array is printed or saved, all layers are printed or saved.

+\subsubsection{Tracking Events}
 
 The PRT Model distinguishes a number of tracking events that can trigger writing of particle track information to binary and/or CSV output files. When a particle track record is written to an output file, the record includes an IREASON code that indicates the type of event that triggered the output. IREASON codes and their associated tracking events are enumerated in the Particle Track Output subsection of the PRT Model Input and Output section.
