Added DotNetBuild=true target in NativeAotTestApp project

[ashutoshjadhav9]

Description

The Asp.Net Core build fails on linux-ppc64le with NU1101 errors for Microsoft.NETCore.App.Runtime.linux-ppc64le and Microsoft.NETCore.App.Host.linux-ppc64le in project src/Components/Testing/testassets/NativeAotTestApp/NativeAotTestApp.csproj. The issue occurs when building Asp.Net Core on linux-ppc64le with .NET SDK 11.0.100-rc.1.26413.103

As Native AOT is not supported on Power Mono Runtime, we are using /p:PublishAot=false and /p:EnableAotAnalyzer=false properties with the build command. These properties should skip the Native AOT related build steps, but the project is still being built and fails during the build.

Error as below

/root/jenkins-scripts/ci/aspnetcore/src/Components/Testing/testassets/NativeAotTestApp/NativeAotTestApp.csproj : error NU1101: Unable to find package Microsoft.NETCore.App.Runtime.linux-ppc64le.

If we add $(DotNetBuild) == 'true' to the project file, the build is successful.

Please scope this to the unsupported rid

This pattern is used in many places without scoping:

aspnetcore/src/Servers/IIS/IIS/test/testassets/TestTasks/TestTasks.csproj

Line 7 in de8ed19

<RuntimeIdentifiers Condition="'$(DotNetBuild)' == 'true'">$(TargetRuntimeIdentifier)</RuntimeIdentifiers>

aspnetcore/src/Hosting/test/testassets/BasicLinkedApp/BasicLinkedApp.csproj

Line 7 in de8ed19

<RuntimeIdentifier Condition="'$(DotNetBuild)' == 'true'">$(TargetRuntimeIdentifier)</RuntimeIdentifier>

Can you help us understand why scoping here is required?
