Implement PalGetModuleFileName for Unix

This change implements PalGetModuleFileName for Unix. Since the module name
passed to us is a utf-8 string, I have modified the signature of the function
to use TCHAR and then modified managed RhGetModuleFileName interop signature
to use byte* for Unix instead of char*. And I have also modified the called
of this function, the TryGetFullPathToApplicationModule, to perform
conversion of that to regular string.
