Subject: [PATCH] Add placeholder properties for emulator

Add some placeholder properties in google VHAL. Developers who use the
aae emulator can use them in developing new features without
implementing a real property.

Bug: 193460353
Test: build aae emulator, use adb lshal to change property values
