The SignVsixInputs target depends on the CopyFilesToOutputDirectory target.  This target logically exists on xbuild but is named DeployOutputFiles.  This descrepancy lead to numerous warnings on Linux during a compilation about missing targets.

After discussing with @jasonmalinowski we decided to move it to
AfterCompile.  This executes in the right place for SignVsixInputs and
is supported in both xbuild and msbuild.

closes #1370

This fixes a couple of build warnings:

- Bad hint path for MS.VS.Platform.VSEditor.Interop.dll
- Syntax.xml did not conform to the prescribed XML schema

I additionally modified VisualBasicSyntaxGenerator to exit with an error
code in the case the provided XML file did not match the schema.  That
will prevent future regressions on the second warning I fixed.

Correct typos

Make the ExpressionCompiler assemblies portable

1. Compile them against Profile7.
   a. Swap out a few APIs (e.g. using GetTypeInfo for reflection).
   b. Introduce an abstraction layer so that we don't have to instantiate
   DkmDataItem (caused a VerificationException).
   c. Include WindowsProxy.winmd as an EmbeddedResource directly, rather
   than through a resx file.
2. Swap the output locations of the ResultProvider projects: Portable goes
to the main output directory and NetFX20 goes to a subdirectory (NetFX20).
3. Include the Portable ResultProvider assemblies in the EE vsix, rather
than the NetFX20 ones.

Fix IsDiagnosticAnalyzerSuppressed check for analyzers that have NotConfigurable diagnostics which are disabled by default.

Current logic didn't account for the fact that even though these descriptors are non-configurable, they might be turned off by default and hence be suppressed.

Code cleanup in the Microsoft.CodeAnalysis project

This adds a bootstrap build step to our Linux verification process.  The
CI test will now build csc and then use that result to rebuild csc.
This will give us verification that we can fully bootstrap our compiler
(on Linux!).

Enable bootstrap builds

The previous name was easily confused with a boolean value.  Changed to
have the Path suffix to make the intent of the value clearer.

this is to disable expensive analyzer (UnusedDeclarationAnalyzer)

This adds a new supported MSBuild property BootstrapBuild.  The value of
this must point to a directory containing a functional version of csc
and vbc.  When specified these executables will be used to build the
product instead of the versions provided in NuGet.

This provides us a very simple way of enabling bootstrap builds.

Fix #1309 : The call to AddTableSource(), which adds the table to
the manager, happens the first time when calling the base constructor
hence a explicit call to the same method is unnecessary and results
in exception being thrown
