Fix CMake race condition in parallel builds

[jreniel]

When compiling with make -jN, a transient race condition can occur where multiple utilities attempt to write .mod files to the shared include directory simultaneously:

f951: Fatal Error: Cannot rename module file '../../include/global.mod0' to '../../include/global.mod': No such file or directory

This happens because utilities like gen_source and interpolate_unstructured define their own module global, and without explicit build ordering, they can compile in parallel and conflict.

Fix: Add add_dependencies() to utility CMakeLists.txt files to ensure utillib is built first, serializing module file generation.

Changes:

• Grid_Scripts: add dependency for interpolate_unstructured
• Pre-Processing: add dependencies for targets using utillib modules
• Particle_Tracking: add dependency for ptrack3
• ArcGIS: fix incorrect schism_geometry link (should be utillib)

Also added a fix for

CMake Deprecation Warning at CMakeLists.txt:9 (cmake_policy):              
  The OLD behavior for policy CMP0074 will be removed from a future version
  of CMake.                                                                
                                                                           
  The cmake-policies(7) manual explains that the OLD behaviors of all      
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW 
  behavior and not rely on setting a policy to OLD.

Tested.

All: please review. These changes seem reasonable.
