Remove Init Data From WB_License_Create

Rather than having init data for the license white-box be passed in
via WB_License_Create, this changes it so that it is assumed that
the private key is compiled into the white-box code.

Minor changes in this code drop include:
  - Updating the git attributes to avoid line-ending conflicts between
    different operating systems

  - Resolving a linking issue seen on Windows

  - Removing default parameter for padding in conformance tests
