Added functions to retrieve tag files/configs

[anutosh491]

Description

Please include a summary of changes, motivation and context for this PR. We should be dependent on compile time definitions for fetching tagfiles and we should be using prefix_path from xeus to do the following at runtime as mentioned in the issue. Hence I've added relevant functions in the xutils.hpp file for the same.

Fixes #54

This PR would probably be worth porting to xeus-cling.
