MdeModulePkg-FPDT(3): Use SMM_FPDT_FUNCTION_GET_BOOT_RECORD_DATA_BY_OFFSET in FpdtDxe.

Browse Source 
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.
