Refactor branch switcher for apollo 3 migration

See merge request gitlab-org/gitlab!79551

The branch switcher in its current state was not
compatible with apollo 3. There were some issues
in the tests that were not supposed to occur. To
fix that, we remove the manual query execution
and instead rely solely on the smart query
execution. Since the query refire as soon
as variables are changed, we can then have
a much safer, automatic way for the smart
query to be fired whenever we need.

* Contributes to https://gitlab.com/gitlab-org/gitlab/-/issues/351520
* Sentry error: https://sentry.gitlab.net/gitlab/gitlabcom/issues/3152528

**Problem**

We don't verify if provided ref exists if it has `.atom` suffix

**Solution**

Return 404 page when ref is missing.

Changelog: fixed

Toggle visibility through a feature flag. Intended as a workaround
before a more permanent solution is built.

REST: Follow shared runners setting

See merge request gitlab-org/gitlab!79448

We previously don't perform `MergeRequestMergeabilityCheckWorker`
when MR `merge_status` is already `checking`. This is to reduce
the number of workers getting enqueued.

However, this can cause a MR getting stuck in `checking` state
in case the worker failed to update the status (e.g. service failed
to obtain a lock). The worker won't be retried because we handle
and log this type of errors.

Since the worker is idempotent, it's already deduplicated. We also
have a lease mechanism in `MergeRequests::MergeabilityCheckService`
that will obtain a lock and keep it for a minute.

We can rely on these mechanisms instead so we can still allow
performing a mergeability check when the `merge_status` is already
`checking`.
