GN requires all actions to have at least one output file. However, many
Python scripts are run to process data without generating a file. Such
scripts would previously have to specify a dummy output file and touch
it on completion.
This change adds this stamp functionality to the script-runner script.
The pw_python_script template accepts a boolean "stamp" argument. If
set, the runner will touch a dummy file after it runs its sub-command.

This change adds a pw_python_script GN template which defines an action
to run a Python script through a script-runner script. This runner is
responsible for resolving any GN paths to filesystem paths, and finding
output binaries for compiled targets. This allows writing Python scripts
which are ignorant of the GN build system and work only with filesystem
paths.
The unit test runner script is updated to use the new runner template.
