Upgrade L3 to v16 and update Android.bp files

Merging CL:
* http://go/wvgerrit/108203
* http://go/wvgerrit/103904 (changes to L3 source files excluded)

Also added ODK dependency which is required by L3 v16.
Do not replace constant sizeof() with a hard-coded value in L3 library because it is target-specific.
