Adds information to executing MuranoPL context that allows to get currently executed method and instruction with its location within source YAML file. All this information can be collected to one stack trace using stackTrace() function and string-formatted using formatStackTrace() Change-Id: Ic0aa4e0b2a87d71f76945feb749ecfb0f5a0d299 Implements: blueprint muranopl-stack-traces
