IntelSiliconPkg/IntelVTd: update PlatformVtdPolicy

Browse Source 
1. Handle flexible exception list format.
1.1 Handle DeviceScope based device info.
1.2 Handle PciDeviceId based device info.
2. Reorg the PCI_DEVICE_INFORMATION
2.1 Merge data pointer reduce allocation times
2.2 Add PCI device id to PCI_DEVICE_INFORMATION
2.3 Rename PciDescriptor to avoid confusing.
3. Fix the debug message too long issue.
