Add avb.vbmeta-version to CompatibilityMatrix and RuntimeInfo

RuntimeInfo fetch avb vbmeta version by reading the following two sysprops:
- ro.boot.vbmeta.avb_version
- ro.boot.avb_version
If the sysprop does not exist, 0.0 is set.

Test: libvintf_test
Test: adb shell vintf (shows 0.0 because CLs
for sysprops are not merged yet)
