Camera: Add support for physical camera characteristics query

- Add version 3.5 for ICameraDevice for physical camera characteristics
query.
- Add version 3.5 for ICameraDeviceSession to work around HIDL
versioning bug.

Test: Camera CTS
Bug: 79523700
Change-Id: I8df6cdd4ee6ac5755758510c0dc1ea1cec31aa73
