Converting this to draft while I work through the build issues.

I consolidated all the patch files into one. This was necessary because I needed to make an additional patch but that was conflicting due to overlap with other patches. So consolidating things made it easier to understand and cleaner.

The change I made was to disable EnablePackageValidation. This is needed because the API compat validation was running into errors like this:

/repos/source-build-externals/.dotnet/sdk/8.0.100-preview.7.23376.3/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.ApiCompat.ValidatePackage.targets(39,5): error PKV006: Target framework .NETFramework,Version=v2.0 is no longer supported in the latest version. [/repos/source-build-externals/artifacts/source-build/self/src/src/newtonsoft-json/Src/Newtonsoft.Json/Newtonsoft.Json.csproj]

The reason for that is:

• Source-build overrides the TFMs to remove .NET Fx
• Newtonsoft.Json is configured to use 13.0.1 as the baseline version for the API compat check. This causes Newtonsoft.Json.13.0.1 to be restored from the dnceng-public feed. That contains .NET Fx TFMs. Since the new package produced by source-build doesn't have these, it leads to these errors.

Please checkout the impact of this flowing into installer. I suspect this will pass because 13.0.1 will get picked up from n-1 artifacts. We should proactively add it to SBRP if that is the case.
