tools: add new tools directory

This is the start of the series of commits focussed on
cleaning up the exmaples/ directory.

This commit moves mraa-gpio, mraa-i2c, mraa-uart files
out of examples directory into new tools directory. Moved
files are the good cadidates to be treated as tools
instead of examples.
