Add logback.xml file in the distributable JAR for the Trigger Service (#13295)

Fixes #13042

changelog_begin
[Trigger Service] Debug logging is now hidden by default. See #13042
changelog_end

Summary of changes:
- remove unused `exports_files`
- refactor trigger-service-binary rules in a single comprehension
- add the `logback.xml` file in the JAR root

Tested manually: listed the contents of the output of `bazel build //triggers/service:trigger-service-binary-ce_deploy.jar` and `bazel build //triggers/service:trigger-service-binary-ee_deploy.jar` before and after the fix, observed that the only difference is the `logback.xml` file in the JAR root; added a debug logger call and ran both JARs before and after the fix, observed that after the fix the debug logging line is no longer printed.
