1. BUGFIX: Enable to customize the suffix of constructor and destructor … …

   …section name
   
   Background:
   
   USD put some functions in section named 'pxrctor', and those functions
   intend to be called to perform initialization work after loading the
   module.  Also, they are expected to be called only once.
   
   Now we have library A was linked to USD build A, and executable B has
   its own USD build B with modified dylib name. USD build A and B are
   different.  USD build A would be loaded first, then get a function lists
   via iterating all sections named 'pxrctor' from all loaded modules, and
   then call each of them. In one word, intialized. After that, while
   loading USD build B, the initialization process would also get a
   function lists in the same way, and it would also contains the functions
   lists collected from USD build A. Again, all functions would be called,
   including those from USD build A. That means those functions from USD
   build A would be called twice. And it leads to crash in our case.
   
   Solution:
   
   Enable to customize and append a suffix to the section name.  the
   corresponding build argument is
   `--build-args=USD,"-DPXR_INIT_SECTION_NAME_SUFFIX=_v2"`
