IfcWrap CMake - migrate to FindPython

Browse Source 
Previously it was giving deprecation warnings:

CMake Warning (dev) at /IfcOpenShell/src/ifcwrap/CMakeLists.txt:38 (FIND_PACKAGE):
  Policy CMP0148 is not set: The FindPythonInterp and FindPythonLibs modules
  are removed.  Run "cmake --help-policy CMP0148" for policy details.  Use
  the cmake_policy command to set the policy and suppress this warning.

  CMake Warning (dev) at /IfcOpenShell/src/ifcwrap/CMakeLists.txt:73 (FIND_PACKAGE):
