Fixed BACnet/SC secure connect VMAC, UUID, and initialization sequence (#1142)

Browse Source 
* Refactored the BACnet/SC datalink initialization order by moving certificate file checks and hub connection registration to occur after datalink initialization
* Replaced stdlib rand() with platform-specific cryptographically secure random functions (RtlGenRandom for Windows, getrandom for Linux, arc4random_buf for BSD) to generate UUID and VMAC addresses, preventing duplicates that broke connections
* Enabled conditional debug output in BACnet/SC components when BUILD=debug is specified
