Adds `Oracle GraalVM` configuration for some backend jobs. `Oracle GraalVM` jobs run only on Linux so far. The old jobs use `GraalVM CE`.
### Important Notes
- The JDK to download and use is deduced from the `JAVA_VENDOR` environment variable. By default, `GraalVM CE` is used.
- sbt can be started with both GraalVM CE and Oracle GraalVM without any warnings.
- If you try to start sbt with JDK from a different vendor, but with the same Java version, a warning is printed.

Removed `enso-types` crate which had only one reference in unused part of the code. Removed some unused dependencies from `Cargo.toml` files.
# Important Notes
CI has a similar hiccup as before. Please disregard this for now in the review.
This PR allows requesting a clean build when triggering the workflow through the manual dispatch.
Previously it was possible only by creating PR and adding the label to it.
This PR adds a native aarch64 target to our release process.
It also includes refactoring of workflow generation and minor tweaks:
* removing some workarounds in the generated action code that are not needed anymore;
* some version bumps that are harmless;
* release builds have cleaning enabled unconditionally.
Now the `clean` CI steps are run always for benchmarking jobs. We run the full `./run git-clean` before and after benchmarks. Benchmarks take long enough to make any savings by not cleaning negligible.
### Important Notes
This PR brings partial refactoring in the workflow generating code which was very dirty. I'll build on this further soon when adding proper aarch64 macOS support.
Also, some minor tweaks to the generation were made:
* not writing `always() &&` twice;
* run only the latter cleaning step for canceled jobs.
