Source-build updates for the .NET 8.0.0-rc.2.23479.6 / 8.0.100-rc.2.23502.2 October 2023 release.

Looks like there are some packages missing from the trusted feeds that will need to be mirrored.

The packages are mirrored correctly. The problem is that the SB artifacts being referenced define which versions are expected in the package feed. But the versions from the SB artifacts are not the same version as those that exist in the feed. This is related to dotnet/source-build#3521 where the build number produced by SB differs from the build number produced by the Microsoft build. To resolve this, we can override the SB version with the expected version that exists in the package feed.

The update in b2459d9 resolved the issue of prep. But now the build is failing:

/vmr/src/command-line-api/artifacts/source-build/self/src/src/System.CommandLine/System.CommandLine.csproj(0,0): error NU1102: (NETCORE_ENGINEERING_TELEMETRY=Restore) Unable to find package Microsoft.NET.ILLink.Tasks with version (>= 8.0.0-rc.2.23479.6)
  - Found 1 version(s) in previously-source-built [ Nearest version: 8.0.0-rc.2.23475.17 ]
  - Found 0 version(s) in source-built
  - Found 0 version(s) in prebuilt
  - Found 0 version(s) in reference-packages

This is because the Microsoft SDK we're dependent is configured to use the Microsoft-built version of ILLink in its BundledVersions.props file. So when attempting to build CommandLine, which uses trimming, the SDK attempts to load that Microsoft-built version of ILLink: 8.0.0-rc.2.23479.6. But the only version that exists in PSB is the SB version: 8.0.0-rc.2.23475.17.

Can this be added as a custom bootstrap package? It would be needed in BootstrapOverrideVersionsProps as well as the buildBootstrapPreviouslySB.csproj

Build is fixed. Please review.

LGTM - friendly reminder to log a follow-up issue to clean this up after the next release
