Share managed EventSource/EventPipe implementation between CoreCLR an…
…d Mono. First changes needed in order to start sharing managed EventSource/EventPipe code between CoreCLR and Mono runtime. Sharable code has been moved into S.P.C library project and split into runtime specific source files when needed, kept within each runtime specific S.P.C project files. Mono runtime has been extended with a set of icalls needed by EventPipeInternal, just to make sure EventPipe can be initialized, current Mono runtime implementation returns dummy values. Current change also enables ETW provider support on Mono Windows runtime. NOTE, this is just initial changes needed in order to share managed EventSource/EventPipe code between runtimes. Future changes will incrementally add EventPipe native code into Mono runtime.
