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

Allow resolving mscorlib with different assembly version numbers

made VS not crash on invalid dll reference (BadImageFormatException). especially for find all reference cache generation (#24452)

* Add UseCultureAttribute to help with culture-dependent unit tests

* Disable NuGet package restore in Visual Studio for Roslyn.sln

* Add named argument for literal

* Fix behavior for NET46 and NETCOREAPP2_0

* Revert "moved waiter from diagnostics.dll to features.dll where all interface… (#24120)"

This reverts commit 823d9730.

* Add references to System.IO.Pipes.AccessControl (#24457)

When adding the reference to System.IO.Pipes.AccessControl for the
compiler server to use on CoreCLR, I unified the pathway for the desktop
and CoreCLR server access control code. This means that
System.IO.Pipes.AccessControl needed to be added as a dependent DLL for
desktop too, but I forgot to do that. This change adds
System.IO.Pipes.AccessControl as a dependent DLL in all the places where
the build task is deployed.

Publish manifest for orchestrated build

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.

* 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
