Autogenerate mobile app LocalBuild.props file

[ViktorHofer]

See src/mono/msbuild/apple/build/AppleApp.LocalBuild.props which contains duplicated version properties like <NetCoreAppCurrent>. Those properties are centrally defined in the root Directory.Build.props file and that file is the source of truth.

Based on @akoeplinger's comment, the intention of that file is to provide setting when used outside of dotnet/runtime. Ideally, for such cases we should auto-generate these settings so that there's only a single source of truth.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.
