Migrating Apple and Android AppBuilder and TestRunner binaries to Artifacts/Bin (#35909)

This PR is a part of #35123. 

This PR achieves two things:
1. Migrates Apple and Android AppBuilder and TestRunner binaries to `<repo-root>/artifacts/bin`
2. Add property paths for Apple and Android AppBuilder and TestRunner projects and binaries

After changes, when building `./build.sh -os iOS -subset Mono+Libs+Libs.Tests`, binary files are no longer produced in `<repo-root>/src/mono/msbuild/`. Instead, they can be found in `<repo-root>/artifacts/bin/`
