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.
