CI: remove `expand-yaml-anchors`

This PR unifies all CI outcome jobs in a single job, and then removes the `expand-yaml-anchors` tool, since it is no longer needed after this change.

I have tested try builds for both situations with the new `outcome` job (note that these two workflow runs use a different step structure in the outcome job, I have simplified it since):
- [Success](https://github.com/rust-lang-ci/rust/actions/runs/8831529677/job/24251135366)
- [Failure](https://github.com/rust-lang-ci/rust/actions/runs/8833052319/job/24251628792)

r? `@ghost`

-#   WARNING! Action needed when changing this file   #
-######################################################
-
-# Due to GitHub Actions limitations, we can't use YAML Anchors directly in the
-# CI configuration stored on the repository. To work around that this file is
-# expanded by a tool in the repository, and the expansion is committed as well.
-#
-# After you make any change to the file you'll need to run this command:
-#
-#   ./x.py run src/tools/expand-yaml-anchors
-#
-# ...and commit the file it updated in addition to this one. If you forget this
-# step CI will fail.

-#   YAML Anchors Definition   #
-###############################
-
-# This key contains most of the YAML anchors that will be used later in the
-# document. YAML anchors allows us to greatly reduce duplication inside the CI
-# configuration by reusing parts of the configuration.
-#
-# YAML anchors work by defining an anchor with `&anchor-name` and reusing its
-# content in another place with `*anchor-name`. The special `<<` map key merges
-# the content of the map with the content of the anchor (or list of anchors).
-#
-# The expand-yaml-anchors tool will automatically remove this block from the
-# output YAML file.
-x--expand-yaml-anchors--remove:
-  # These snippets are used by the try-success, try-failure, auto-success and auto-failure jobs.
-  # Check out their documentation for more information on why they're needed.
