DynamicTablesPkg: Adds X64 FACS generator library

Browse Source 
Adds a library to generate the ACPI FACS table for X64 architecture.
It gathers the necessary FACS information from the configuration manager.
Additionally, it includes an event to update the hardware signature
in the FACS table, where the hardware signature is the
CRC of all ACPI table's CRC
