pytest: add sandbox test for "extension" command
This commit extends the sandbox to implement a dummy extension_board_scan() function and enables the extension command in the sandbox configuration. It then adds a test that checks the proper functionality of the extension command by applying two Device Tree overlays to the sandbox Device Tree.
