Add separate dependency tags for compat libs based on SDK version.

The version in the tag is the SDK version that in which compatibility
library was added as a separate libary. Using distinct tags makes it
possible to differentiate between dependencies for different SDK
versions (this will be needed in subsequent CLs).
