A skeleton of a classpath fragment's interface and base to be used by any modules that provide entries for *CLASSPATH variables at runtime. In follow up changes, this would be extended to generate packages/modules/SdkExtensions/proto/classpaths.proto configs for such modules to be bundled into system and individual apex binaries. Bug: 180105615 Test: m Change-Id: I2df550862e97222c5650c4d0480c90231fd78ef0
