feat(actions): update actionslib, support self:, misc fixes (#39358)

Updates actionslib to https://gitea.com/gitea/actionslib/releases/tag/v1.2.1, moves workflow
parsing into it and aligns behaviour with GitHub.

1. `uses:` supports `self:` (Gitea-only feature) and `$/` paths.
1. `strategy`, `matrix`, `max-parallel` and `fail-fast` accept
expressions, including over `needs`. A job whose `name`, `runs-on` or
`continue-on-error` reads `needs` is resolved once they finish.
1. A job `if:` may only read `github`, `needs`, `vars` and `inputs` and
is decided before the matrix, as on github.com.
1. Matrix `fail-fast` cancels the other combinations, and `always()`
jobs keep running when a run is cancelled.
1. Invalid workflow files, including a malformed `on:` and unknown or
cyclic `needs`, show up on push as failed runs with the error.
1. A job whose `if:` or `concurrency:` fails to evaluate is skipped or
failed with the error, instead of staying blocked.
1. Reusable workflows: a missing and an unreadable repository fail
alike, public callers cannot use private workflows, nested jobs cannot
exceed the caller's token permissions.
1. Runner labels match case-insensitively, and `runs-on` accepts an
array from an expression.
