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. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@5380 6f19259b-4bc3-4df7-8a09-765794883524
