SecureBoot: Driver signing

Systems may require enhanced validation of the Windows drivers. This is usually the case with systems with enabled SecureBoot.

In this case, the TwinCAT C++ drivers must also be signed by the "Attestation Signing" established by Microsoft in the same way as all other drivers that the operating system is to load. The procedure for this is documented in MSDN.

For development purposes, the development process can be simplified on corresponding test systems by deactivating SecureBoot.
