Revert "Add a StyleCop step to the build script"

This reverts commit 3272b0c67896d16acaddc8ae0115ec1c6eef5215.
# Updated to set file name of script engine
# Added RoslynScriptDllGeneratorEngine.cs which saves generated file to .dll
# Simplified implementation of different engines. Updated composition root to have separate engines for scripts and repl.
# Updated constructor to be protected in abstract class
# Updated to generate .dll inside bin folder
Stopped writing .pdb file to disk, as it cannot be manually loaded into VS (error is thrown). Debugging can be achieved by running in memory.
