Changes our blob publish to include the manifest file. Needed by more
recent versions of product build.

Also decided to just link our two msbuild files together via MSBuild
task vs. a powershell script. The point of microbuild.ps1 is to test as
much as possible in our jenkins build. There is no way to actually test
blob publishing in Jenkins hence this indirection was just causing
problems, not helping anything.

Localization test failures 3

* changed our service name to include roslyn.

it is asked from service hub team so that they can more easily identify which team owns which service.

* update devdiv insertion tool for the renames.

Move compiler core tests to use netstandard2.0 RTM

Fixed VS2017 crash with :: operator

It was still relying on the 'ref' directory. Changed it to use the
resource image.

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

Added support for pattern matching syntax to smart variable completion provider

Suppress analyzer for properties with explicit interface implementation

Merge dev15.6.x to dev15.7.x

Now that the netstandard2.0 references are available via the
MS.CA.Test.Reosurces.Proprietary NuGet package we no longer need to copy
them around on the file system (that's where they were previously being
referenced from).

This changes the reference assemblies we use for the CoreClr compiler
compilation to be Net Standard 2.0 RTM. Previously they were a beta
version.

This did mean a number of tests had to be moved to be desktop specific
again. This is primarily due to the presence of ValueTuple as a default
type in Net Standard 2.0. Tests that relied on ValueTuple not being
defined had to be moved to net461 which doesn't have that type defined
by default.
