DynamicTablesPkg: DynamicTableManagerDxe: Refactor PresenceArray
Mandatory ACPI tables depend on the architectures.
Different architectures might also want to check other tables.
Move mAcpiVerifyTables containing the list of ACPI tables to check
to an arch specific file and introduce GetAcpiTablePresenceInfo()
to get get the relevant information from the array.
