VTS: Add test for device version 3.5

Also includes:
- Add test for getPhysicalCameraCharacteristics.
- Doc update for the new HIDL API.
- Tighten boundary check for camera ID in CameraModule.

Test: vts-tradefed run commandAndExit vts --skip-all-system-status-check
--skip-preconditions --module VtsHalCameraProviderV2_4Target -l INFO
