* Remove harvesting of M.E.DependencyModel

The netstandard1.6 configuration of Microsoft.Extensions.DependencyModel
isn't built anymore. Instead the already built matching binary from the
latest available package version is redistributed when packaging the
DependencyModel library.

Also dropping the netstandard1.3 asset and the net451 one as the
minimum supported set of platforms are ones that support netstandard2.0.

In addition to the harvesting removal, cleaning up the src project which
had an unnecessary condition and property set.

Contributes to https://github.com/dotnet/runtime/issues/47530

* Move DependencyModel to libraries

Moving DependencyModel to the same folder and infrastructure as the rest of our libraries, and out of the installer folder.

I also dropped support for anything below netstandard2.0 at this time.

Contributes to #3470
Fix #3425

* Exclude DependencyModel in shims and package checks since it has a duplicated type with System.Collections.

* Harvest previous TFM assets from the previously shipped package.

This also means we start building DependencyModel for net461 to ensure full framework support works correctly, and doesn't pick up the old net451 asset.

* Fix unit tests to consistently pass on core and netfx.

* Add back HashCodeCombiner as obsolete.

* Fix DependencyModel pkg build to reference the correct version of Newtonsoft.Json for the harvested package assets.

* Adding IgnoredTypes for Serialization.Primitives in netcoreapp1.0 and netcoreapp1.1

This ports the type model and C#/VB code generators to corefx; compilation to assemblies is currently not supported (we could potentially layer that on top of Roslyn subsequently).  I also ported a bunch of tests, though there's lots of room for improvement on the test suite.

Ports the .NET Framework implementation to corefx and adds some tests.  There is a large portion of the implementation that's internal and not actually reachable from the exposed surface area, but exists to support SmtpClient.  I've left that code in so as to enable subsequent porting of System.Net.Mail; at that point, we may want to combine all of this into a System.Net.Mail contract, but for now I've left it in a System.Net.Mime one.

This elevates the minimum supported framework for S.S.C.OpenSsl to
netstandard1.6.

Let GenApi rewrite the contract file to include all of the new overrides, plus the new constructor.  Since the type is sealed the overrides aren't all that important, but the new constructor is only callable with the new contract.

These are no longer needed with the latest buildtools.  They'll be
harvested just like other dependencies.

This adds dummy implementations for platform specific API.  The
implementation assemblies throw PlatformNotSupported for all methods.

This will satisfy NuGet's guardrails check and also let folks compile
against these assemblies and load them at runtime without JIT failures.

We will not be placing these packages in any of the shared-framework
layouts, nor should any of these ever be depended on by CoreFx
libraries.  But we will provide them to enable folks to write platform
lightup code without having to worry about using reflection or guarding
calls in separate methods disabling JIT inlining.

These assemblies are marked with AssemblyMetadata("NotSupported",
"True"), so that future dev-time tooling can detect them and warn/error
in the case of accidental dependence on platform specific API.

One notable difference is
System.Runtime.InteropSerivices.WindowsRuntime: this assembly was
previously part of portable profiles and implementation exists in
mscorlib.  For this we will forward to mscorlib on all platforms and it
is up to mscorlib to determine implementation (throw vs noop).
Fixes https://github.com/dotnet/corefx/issues/6684

Other platform specific contracts that have been excluded:
System.IO.IsolatedStorage: currently only supported for netcore50 so no
need to address this problem for x-plat.
System.Runtime.WindowsRuntime & System.Runtime.WindowsRuntime.UI.Xaml:
both are WinRT specific and not exposed in any PCL profiles that we
expect folks to use with x-plat NET core.

We don't currently have a cross-platform API for folks to use to create
and RSA object https://github.com/dotnet/corefx/issues/2953, and dotnet
cli doesn't yet support folks cross compiling by platform
https://github.com/dotnet/cli/issues/465.

As a result, this package was failing to restore when dotnet CLI
switched to NuGet which will detect missing support at build
time instead of allowing a file-not-found at runtime.

Temporarily unblock installation of this package on Windows so that
folks can consume the package until we have an x-plat API.

After this change if you build a .builds file it will all projects
defined in it. However if you specify OSGroup or FilterOSGroup as a property
it will only build the projects that are for that OSGroup or AnyOS.

Change the default OSGroup to AnyOS instead of Windows_NT.

By default if you build from the root it will only filter the projects to
just the OS that you are building on (including anything that is AnyOS).

If you want to build all projects for all OS's from the root pass
/p:BuildAllOSGroups=true property from the command line.

Includes an update to project-guidelines.md and windows-instructions.md docs
with information on the changes.

This change switches the TFS package buid to use the packaging
infrastructure from the buildtools package.  For any package
project that exists in corefx/wcf we will use that in place of the
closed source package.

As we move more package projects to the open they will
automatically be preferred over the closed source projects.
