MdeModulePkg-FPDT(3): Use SMM_FPDT_FUNCTION_GET_BOOT_RECORD_DATA_BY_OFFSET in FpdtDxe.
This patch enhance performance data SMM communication by using fixed SMM communication buffer. Update FpdtDxe to use fixed SMM communication buffer to get performance data by SMM_FPDT_FUNCTION_GET_BOOT_RECORD_DATA_BY_OFFSET API. This is designed to meet Microsoft WSMT table definition on FIXED_COMM_BUFFERS requirement.
