chore: create release cloudbuild yaml for library_generation (#2510)

# In this PR
- We add a new `cloudbuild` yaml that is configured to push a new image
tagged as
`gcr.io/cloud-devrel-public-resources/java-library-generation:${_GAPIC_GENERATOR_JAVA_VERSION}`
 - We reorganize the folder structure of `sdk-platform-java/.cloudbuild`

## The new trigger
It's called `library-generation-sdk-platform-java-release`

# Before merging this PR
- [x] Update _all_ library_generation triggers to point to the new
location (`.cloudbuild/library_generation`)
 - [x] Get approval from @mpeddada1 in order to:
- [x] Update graalvm __test__ triggers to point to the new location
(`.cloudbuild/graalvm`)
- [x] Update graalvm release triggers to point to the new location
(`.cloudbuild/graalvm`)
