Port EdkUnixPkg to UnixPkg. The changes are listed as follows:
1. change *.msa to *.inf, and create platform configuration files .dec&.dsc&.fdf to comply with Edk2 build process
2. using PCD mechanism to replace macro.
3. change Sec code to cowork with PI1.0 Pei Core and produce temparory memory ppi.
