Use CPM in Binary Tool

[ellahathaway]

Fixes dotnet/source-build#4487

In order for the binary tool to use the versions of the packages specified in CustomPackageVersionsProps, we need to specify that we are using CPM.

Templating repo failed in the linked build, but it appears unrelated to the changes in this PR.

Interesting. What changed that makes this now necessary?

From what I can tell, the change that brought in this error was an upgrade of the version of nuget that we're using: https://dev.azure.com/dnceng/internal/_git/dotnet-dotnet/commit/aa327a6db9bba39f54a57b1d4c04c6ab2dace340?path=/prereqs/git-info/nuget-client.props (internal link)

Otherwise, nothing changed with the tool itself or the scripts we use to configure it to suddenly cause this.

Timeout in CI - Seems like it's related to #40074

I noticed that this isn't enough any only fixes the "Prepare for build" job. CPM in general got broken in dotnet/dotnet but is only observable in a stage2 build. I submitted #41895. This PR shouldn't be needed anymore.

Oh great, thanks Victor! I'll close this PR
