Install Python Packages System-wide for Python > 3.10

[danthony06]

#880 addresses problems with rosdep, pip, and Python versions newer than 3.10. Installing pure Python dependencies with rosdep is broken with Python 3.11 and above because pip will not install into the system-wide Python location without extra configuration. For more information on this, see the links at the end of this issue.

#885 allows settings PIP_BREAK_SYSTEM_PACKAGES more conveniently.
I do not want to set it by default for now.
