This API is available since 5.5.1 (released in 2022) and allows us to
avoid the inefficient previous implementation (don't think it's worth
keeping that around for older versions). Also added support for
SHAKE-128. Note that the only user of SHAKE is the ml plugin nowadays
and since wolfSSL also provides ML-KEM, this might not actually
get used much.
Let's try this again :) Since cache entries with the same key are not
updated/replaced and there is no option to do so, we manually delete the
previous entry for the current branch.
This reduces the cache storage for active branches, which can cause
caches of the master branch to get evicted, which in turn will slow down
builds of not only master but also new branches as they can't fall back
on those caches.
Permission has to be explicitly granted in order to delete the cache
entries when not using the legacy all-write tokens that are the default
for old repositories.
The continue-on-error option is set for the step that deletes the old
cache entry as it's expected that cache-hit will be true for a new feature
branch when restoring the cache from the master branch. However, because
there won't be anything to delete for this branch yet, the command will
fail. The --succeed-on-no-caches option of the command unfortunately
only works with --all.
For the Linux tests, several jobs use the same cache key. So there is
a chance that two jobs try to store a new entry concurrently, which will
fail (it works if there was a cache hit and they are slightly off as
previous entries are first deleted). To avoid that, we store the cache
only for one particular config.
Also made sure that the "openssl" test does not remove "openssl-3/4"
caches by adding a suffix to the former.
For alpine, the repository had to be set explicitly as gh wasn't able to
determine it (didn't detect the Git working dir).
