Provide a way to disable trusted device.

Add CarManager APIs for
1. Disable/Enable Trusted device Enrollment
2. Disable/Enable Trusted device unlock
3. Remove all of the trusted devices.

A privileged client can use the above options to come up with their own
policy to handle a lost/stolen phone scenario.

Also added a way to execute the above options from adb car shell.

Bug: 128439243
Test: Enable/disable trusted device feature by calling the methods from
adb car shell (ICarImpl)
