Don't pass undefined context-values to Labkit

See merge request gitlab-org/gitlab!22999

Don't pass values on to labkit that weren't explicityly
defined. Otherwise, labkit will unintentionally overwrite any existing
values with nil.

Consider the following example:

  ApplicationContext.with_context(user: <User "jane-doe">) do
    ApplicationContext.with_context(
      project: <Project "gitlab-org/gitlab">
    ) do
      # The inner context lives here
    end
  end

We want the inner context for Labkit to contain this hash:

  {
    user: "jane-doe",
    project: "gitlab-org/gitlab",
    root_namespace: "gitlab-org"
  }

But before this change, we'd overwrite the `user` value when creating
the inner context, even though the inner context did not contain any
information that should override the user info.

Avoid bug where owner ends up unable to log in due to SSO enforcement,

Long term we will offer to convert the user to a Group Managed one, so
would be able to remove this workaround.

Implement AtomicProcessing service

See merge request gitlab-org/gitlab!20229

This implements atomic processing service
that is able in bulk to update multiple builds,
stages and pipelines.

This uses in-memory structure to calculate statuses
and uses an efficient fetch of DAG dependencies
for efficient processing

This still performs some redundant operations,
but overall it should be significantly faster
processing pipelines of 1000 builds, with
multiple DAG dependencies, as it removes
a number of N+1 problems present in previous
implementation.

This also is order-independent, so it is able
to easily reschedule itself once needed.

This code is also concurrent safe, as if needed
the further processing will be re-scheduled
that will resolve any conflicts.
