Commit migrated from https://github.com/dotnet/core-setup/commit/162bce049b29efe47f8ea2992c5d26d2ccdbc728

Update BuildTools to prerelease-02103-02

Commit migrated from https://github.com/dotnet/core-setup/commit/d03b39df5ff081df471255fc1310c3ba3fcdd854

Handle RIDs better during the build.

Currently, when building non-portable on a win10 machine, core-setup restores and produces `win7` RID assets.  This causes problems in source-build since corefx produces `win10` assets on the same machine. Thus, core-setup can't use the corefx assets because win10 is not compatible with win7.

In fixing this, I refactored the way RIDs are handled during the build.  We have 3 main RID usages:
* What is the RID of the current machine?  $(HostMachineRid)
* What is the RID of the toolset we are using to build?  core-setup doesn't have this scenario yet, but corefx calls this $(ToolRuntimeRID)
* What is the RID that the current build is producing outputs for?  $(OutputRid)

Fix VersionSuffix for the managed projects

VersionSuffix is getting set before $(BuildNumberMajor) and $(BuildNumberMinor) are being set.  When creating the DependencyModel nupkg, it is getting a bad version on its p2p reference to PlatformAbstractions.

The fix is to ensure VersionSuffix is defined correctly in the projects themselves - after the obj\BuildVersion.props file is created.

Fix PlatformManifest generation

When we generate the PlatformManifest.txt, and an assembly doesn't have a valid FileVersion, we are never updating the first entry that gets put into the fileVersions collection.  This is because the check for AssemblyVersion only updates the entry if both current and existing AssemblyVersions are non-null.

Fixing it check for current != null and existing == null, to update the entry.
