Camera: Add fall back properties for FMQ size override

All system properties in the vendor partition must
start with either "vendor" or "ro.vendor".
Older devices should not be affected but newer
implementations may not be able to override the
FMQ size if needed.
Keep this functionality and provide fall back
properties using "ro.vendor.camera".

Bug: 77865891
Test: Manual using application and modified device configuration.
