This reverts merge request !31361

Support selective highlighting of lines

See merge request gitlab-org/gitlab-ce!31361

Instead of highlighting all lines when not all of them are
needed, only highlight specific lines.

The `BlobPresenter#highlight` method has been updated to
support `since` and `to` params. These params will be used to
limit the content to be highlighted.

Modify `Gitlab::Highlight` to support `since` param which will
then be used to determine the starting line number.

This commit changes how we eager-load projects, routes, and namespaces
required by the deploy keys endpoint, getting a 10x improvement in my
local testing.

The endpoint still doesn't scale in-general, but going from ~13 seconds
to dump a 63K result to generating the same thing in ~1.6 seconds seems
like a good improvement to me.

These are not required because MySQL is not
supported anymore

Return the `text` as plain string in the response instead of
including HTML tags but keep `rich_text` as is.

The fix is to modify `Blob::UnfoldPresenter#diff_files` to map
each raw diff line (limited by the range specified) to a
corresponding line in an array of highlighted lines to use as
`rich_text`.

Adding new `AddAwardEmoji`, `RemoveAwardEmoji` and `ToggleAwardEmoji`
GraphQL mutations.

Adding new `#authorized_find_with_pre_checks!` and (unused, but for
completeness `#authorized_find_with_post_checks!`) authorization
methods. These allow us to perform an authorized find, and run our own
additional checks before or after the authorization runs.
