Control lid behaviour with a Global setting

Using a global setting to specify the lid open/close behaviour
allows OEMs to support switching between windowed and windowless
lids at runtime instead of build time.

Bug: 70378569
Test: Find the hall effect sensor on the device and then using a magnet
confirm the expected behaviour for each global setting:
* No reaction from device
adb shell settings put global lid_behavior 0
* Sleep/screen off
adb shell settings put global lid_behavior 1
* Lock screen but screen stays on
adb shell settings put global lid_behavior 2
