When we added caching, this meant that calling `can_be_resolved_in_ui?` didn't
always call `lines`, which meant that we didn't get the benefit of the
side-effect from that, where it forced the conflict data itself to UTF-8.

To fix that, make this explicit by separating the `raw_content` (any encoding)
from the `content` (which is either UTF-8, or an exception is raised).

For each event with `Event#target_type` of "Note",
we had a query to load the associated instance `noteable`.

For example, if `Note` was related to an issue, we'd load each `Issue`
with its own query (N+1 problem).

Closes #43150.

Now the issuable reference check works only in project scope, if we
reference an issuable from a non-project resource (e.g. epics), then
project is not set, and there is mismatch in generated issue references.

This patch enables issuable reference state check also from group scope.

These limits were updated in our docs, and in omnibus some time ago. But
the defaults in the source-install were missed.

When the database is in a read-only state, display a banner on each

Before we were using a "plumbing" Gitlab::Git method that does not go
through Gitaly migration checking.

Previously, this would issue a query for each unique `diff_refs_or_sha`
passed. This was because we didn't want to load other MR diffs into memory, as
they had some very large columns.

Now they are actually very small, and it's more efficient to just load them all
at once and do the finding in Ruby.
