Don't generate `.mo` files

See merge request gitlab-org/gitlab-ce!20048

If `current_signin_tab` is `#crowd`, then no tab will be active. Fix
this by using the first available tab.

Resolve "Web IDE "Commit" button should indicate when there's a subsequent step"

Closes #48133

See merge request gitlab-org/gitlab-ce!20030

Since we are only using `.po` files for translation we can shave off
some setup time.

Generating the `mo` files also regenerates the PO-files, including
fuzzy translations. Those cause a lot of bugs, and we don't need them
anymore since the `po` files are generated by an external translation service.

There is still the edge case when 'no commits' changes to 'conflict'
would not trigger notification, which we ignore for now.

Calling can_be_merged? can cause exception (e.g. non-UTF8)
Ignore those by rescueing.

Remove unmergeable_reason as now only conflict is notified

Fix: Serve favicon image always from the main GitLab domain to avoid issues with CORS

Closes #47802

See merge request gitlab-org/gitlab-ce!19810

In MR https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/15834 we
removed use of the data produced by the Allocations Gem. However, we
never removed the code that just enables tracking of allocations. In
this commit we remove all remaining traces of this Gem.

This makes the output in static analysis a bit more verbose.
