DynamicTablesPkg: Correct parser for X64 architecture objects

[abdattar]

• Add array size to CmArchCommonSpmiInterfaceInfoParser to correctly parse the SPMI interface object.
• Use the size of enum values instead of fixed sizes.
• Apply #pragma pack to the X64 object structure to ensure the total size of the structure matches the parser's combined individual field sizes without padding.
