Of course, this means that there's a bunch of logic
to coordinate the new flag with the original -
`automaticallyCollapsed` - flag.

In addition: the UI is updated to use the new flag
whenever it's been set, but to continue to fall back
to the old flag. This is primarily facilitated by a new
helper utility for diff files to do the resolution in a
single centralized place.

Of note: the diff_file is updated to depend on the
global store as the authoritative source of determining
whether the file is collapsed or not. The previous
version kept a local `isCollapsed` in sync with the
global store, which introduced a huge amount of
interwoven complexity. The update ingests the
resolved collapsed state from the store when
various observed properties update instead of
inverting that flow.

This is a full refactor of file collapsing.
Because the previous version was a single flag, then
modified with a user preference (file-by-file), there
were some issues including a THIRD possible way
that collapsing works. This update slightly simplifies
how collapsing works by depending more heavily
on the two flags stored in state and only modifying
them with the user preference when necessary.

[RUN ALL RSPEC] Fix migrate-from-v12.10.0 job not working with Ruby v2.7

See merge request gitlab-org/gitlab!46073

This test needs bundler v1.17.3 to work, so install that first.

The grpc and google-protobuf gems need to be updated to work with Ruby
v2.7. When we check out the v12.10.0-ee tag, we manually patch the
versions in the Gemfile before attempting to run the migration.

Fix Merge Request "Edit in Web IDE" dropdown link on MR diffs page

See merge request gitlab-org/gitlab!45653

As seen in QA pipelines and discussed in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/42229, the Grape
API initialization would fail if the database were empty. We now check
the existence of the `features` table to prevent this from happening.

This still does not allow us to change the feature flag dynamically, but
it unblocks the test failures.
