Graph builds don't handle GeneratePackageOnBuild when the project multitargets and is referenced

[dfederm]

Issue Description

If a project multitargets, uses GeneratePackageOnBuild, and is referenced by another project in the graph, the Pack target is not run.

Steps to Reproduce

Library\Library.csproj (multitargets and has GeneratePackageOnBuild):

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFrameworks>net472;net7.0</TargetFrameworks>
    <GeneratePackageOnBuild>true</GeneratePackageOnBuild>
  </PropertyGroup>
</Project>

Library2\Library2.csproj (references Library.csproj):

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFrameworks>net472;net7.0</TargetFrameworks>
  </PropertyGroup>
  <ItemGroup>
    <ProjectReference Include="..\Library\Library.csproj" />
  </ItemGroup>
</Project>

repro.sln (just a sln containing the two projects):

		{4791B1D6-0EAA-4630-A009-E93336BEDA5C}.Release|Any CPU.Build.0 = Release|Any CPU
	EndGlobalSection
EndGlobal

Expected Behavior

Library\bin\Debug\Library.1.0.0.nupkg is created.

Actual Behavior

Library\bin\Debug\Library.1.0.0.nupkg is not created.

Analysis

In this scenario, the only target that executes on the outer build of Library.csproj is GetTargetFrameworks. If one were to remove the reference from Library2.csproj, the Build target gets executed, which then hooks Pack due to GeneratePackageOnBuild.
