This refactors the implementation of gathering/iterating changes
from the post-receive hook to be a bit more readable (removed
the need for calling `enum_for(:changes_refs)` in different
places).

This is done with the help of the new `Gitlab::Git::Changes`
collection object which will be used while parsing the changes.

Also changed the signature of BranchPushService and TagPushService
to accept a single `change` param instead of having oldrev, newrev
and ref params.

This also prepares the `PostReceive` worker to be able to process
branches and tags separately so we'll be able to aggregate events
by branches or tags.

Only schedule updates of remote mirrors once per push

See merge request gitlab-org/gitlab!17902

Before we were scheduling the update once for each pushed ref through
the Git::(Branch|Tag)PushService. But all the refs will be pushed
every time, meaning that most of these updates would be no-ops.

This moves the updated out into the PostReceive worker, so this is
only scheduled once per push.

This commit adds a new vuex store module to the security dashboard.

(ee/app/assets/javascripts/vue_shared/dashboards/store) but includes
some changes that aim to make it more generic.

Return unloaded commit if  it couldn't be enriched

See merge request gitlab-org/gitlab!17894

When a commit could not be enriched, we want to return the original
commit.

When calling `Commit.lazy` we get a `BatchLoader` instance that
behaves like `nil`. So now we explicitly trigger the loading in batch
and replace the commit with the original commit if it could not be
loaded.
