Add userRestriction attribute in Location settings injector.

We would like to disable location accuracy ui in Settings when DISALLOW_CONFIG_LOCATION is set.
As disable location accuracy preference in Settings is injected from GmsCore, we would like a way to identify which injected settings is location accuracy.
So we want to add an additional field here: https://cs.corp.google.com/piper///depot/google3/java/com/google/android/gmscore/integ/container/proxies/location/base/res/xml/location_accuracy_injected_settings.xml?q=SettingInjectorService+file:%5E//depot/google3/java/com/google/android/gmscore/integ/+package:%5Epiper$&dr=C
Thus we need to update attributes in framework

Bug: 72633181
Test: manually by replacing userRestriction in attrs.xml with an existing
attribute "id", change location_accuracy_injected_settings.xml in gmscore to
include user restriction value, and tested Settings UI via TestDPC
