Subject: [PATCH] Add printout of picotool location (#2475)

This prints out the location of the picotool executable being used

For example:
* `Using picotool from /usr/local/bin/picotool` for a system install
* `Using picotool from /home/name/pico-examples/build/_deps/picotool/picotool` for a picotool fetched by the SDK
