This PR fixes the CoreCLR compiler server on Windows and changes our bootstrap 
build to act as a test case. The build was previously failing during pipe ownership verification
because the required API was not available through reflection. This change
uses the System.IO.Pipes.AccessControl API to do pipe ownership verification
instead. However, System.IO.Pipes.AccessControl is operating system dependent 
and thus ends up in the runtimes subdirectory next to the build task.
Unfortunately, there is no mechanism for automatic assembly resolution
of plugin DLLs like MSBuild tasks, so we have to implement something
similar ourselves. This change hooks assembly resolution and, when we
see a well-known DLL request, we redirect it to the appropriate path.

Fixes #20900 and #24072

Add satellite assemblies for the Roslyn assemblies that we ship in
Microsoft.NETCore.Compiler.nupkg. This includes
Microsoft.CodeAnalysis.dll, Microsoft.CodeAnalysis.CSharp.dll,
Microsoft.CodeAnalysis.VisualBasic.dll, and
Microsoft.Build.Tasks.CodeAnalysis.dll.

This increases the resulting .nupkg size from about 8,988KB to about
12,000KB.

This change adds the git commit which produced the NuGet package to the
description section. This makes it easy to both

- Determine what source is included in a NuGet
- Determine if a given change is included in our NuGet

Lacking this only way to understand which commit produced a NuGet is to
download the NuGet, crack open the binary and look at the version we
embed into the PE. This allows us to see the version on the NuGet page
itself.

This reverts commit 8a1ca479 and moves
publish earlier in the build pipeline (before signing) to prevent
published binaries from overwriting already built and signed binaries.

This reverts commit 2d36e419.

This change was causing the signed build to break due to publish
overwriting previously built and signed binaries.

Creates a new package, Microsoft.NETCore.Compilers, which contains
CoreCLR-compatible versions of csc and vbc compiled against the
netcoreapp1.1 shared framework. This NuGet package can be referenced
by any C# or VB MSBuild project as long as the `dotnet` command line
tools and the netcoreapp1.1 framework is installed.

* update NETCore.Compilers nuspec

* Update portable facades file

Creates a new package, Microsoft.NETCore.Csc, which contains a Csc
binary compiled against the netcoreapp1.1 shared framework. This can be
installed as a NuGet package and built using the dotnet SDK, as long as
the netcoreapp1.1 framework is installed.

This change also downgrades a few packages, like
System.Diagnostics.FileVersionInfo, that were higher than the
version available in netcoreapp1.1.
