pw_arduino_build: Support Multiple Library Paths
- `--library-path` can take multiple paths in order of increasing
precedence similar to Arduino IDE behavior. This is useful for
including the 'libraries' directory included in an Arduino core
and a separate user library folder.
- Remove serial wait loop from pw_sys_io_arduino
- Fix raised ValueError if arduino core install prefix is not
relative to os.getcwd()
