[Tracking] Overhead of SDK build targets is too high for a normal build

[davkean]

This is a normal build version of #1496 with a single project targeting .NET Core 2.0, running on 15.3.2:

msbuild "C:\Users\davkean\Source\Repos\ConsoleApp90\ConsoleApp90\ConsoleApp90.csproj" /clp:Summary;PerformanceSummary;v=m

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>

</Project>

Comparing it against a default .NET Framework 4.6.2 project, it is 100% slower (620ms vs 311ms) on an up-to-date build:

This does not include:

• Evaluation time
• MSBuild launch time
• Restore time
