DynamicTablesPkg: Extract AcpiHelperLib from TableHelperLib
The TableHelperLib contains helper functions. Some rely on DynamicTablesPkg definitions (they use Configuration Manager objects). Some others are more generic. To allow using these generic functions without including DynamicTablesPkg definitions, move them to a new AcpiHelperLib library.
