rules: Add automatic suspend udev rules

The ChromeOS ecosystem has a large amount of testing, both automated
and manual across devices including measurement of power regressions.

It's safe to assume that any of these devices will handle USB
auto-suspend appropriately.  Use the script from ChromeOS
https://chromium.googlesource.com/chromiumos/platform2/+/master/power_manager/udev/gen_autosuspend_rules.py
to generate udev rules at build time.

This script in systemd `tools/chromeos/gen_autosuspend_rules.py` should be kept
in sync with the ChromeOS version of the script.

Manually added autosuspend devices should be placed in the new
template `rules/61-autosuspend-manual.rules`
