This commit makes it so that we will always try to generate release nugets except if they depend on prerelease packages. If one of our nuget packages happens to depend on prerelease packages, then when building release nugets, we will simply print a message in the build output and skip release nuget generation for that package (and allow the overall build to succeed).

Add support for an OperationTreeVerifier - test only OperationWalker to dump operation tree. (#11918)

The dump approach should enable to us to (relatively) easily extend the existing C# and VB binding tests to verify the operation tree.
I have moved the existing IOperation tests to the dump approach and also added couple of additional tests to demonstrate how to write these tests for entire method body operation tree verification.
