This adds two new properties alongside AndroidVersion.ApiLevel:
- AndroidVersion.ExtensionLevel: The sdk extension version if the SDK
- AndroidVersion.IsBaseSdk: Whether the extension level is the the one
that the ApiLevel shipped with (true), or if is an extension SDK
release (false).
While we're here, dedupe the recipe that processes these templates.

(cherry picked from commit cf2f42c36b7997e9ce87682bb3a5511bdb72936f)
This adds support for "templates" source.properties files that can
inherit the platform version/codename/api level from the build.
The purpose is for a given build to always generate SDK files that
match the platform generated in the same branch.
