Add custom java_sdk_library info to the SDK info file

Previously the SDK info file only contained basic common information
about each member. This change adds support for each member to
provide custom information to add to the info file.

It uses that mechanism to add the following:
* "dist_stem"
* "scopes" object containing:
  * for each scope a:
    "<scope>" object containing:
    * "current_api" - the path within the snapshot for the API's .txt
                      file.
    * "removed_api" - the path within the snapshot for the removed
                      API's .txt file.
    * "latest_api" - the path within the build to the latest finalized
                     API .txt file.
    * "latest_removed_api" - the path within the build to the latest
                             finalized removed API .txt file.

In order to access the latest API files it was necessary to add and
resolve dependencies on the module that makes them available. In order
to do that safely the code for creating the names of the modules was
refactored to avoid duplicating the name creation logic.
