pack template for custom analyzer (#10155)

Fixes #9915

Context
#9789 added a template for custom analyzer.
In order for that to be usable by our customers - we need to be publishing this to nuget feed along with our other binaries. So we should have the package produced from our repo - ideally as part of our build script

Changes Made
Create a template package project with property <GeneratePackageOnBuild>true</GeneratePackageOnBuild>that pack the templates into a nuget package when build. Add the package project in the msbuild solution in order to build the project.

Testing
https://dev.azure.com/devdiv/DevDiv/_build/results?buildId=9602998&view=artifacts&pathAsName=false&type=publishedArtifacts in the packageArtifacts folder.
