Rename `repo_lang_stats_test.go` to `linguist_test.go`, and add a new
tests that exercises parts of the web UI to ensure that language
overrides in `.gitattributes` work when viewing a file source, and in
the blame view too.

There are a number of tests which require creating a repository on the
fly, and they each do it their own way. To reduce code duplication, lift
out this common pattern into a helper called `CreateDeclarativeRepo()`,
which lets us create a repository, set up enabled and disabled repo
units, and even add, delete, or update files.
Also convert a number of users of this pattern to the new helper - those
users that I introduced, and are in code introduced by Forgejo in the
first place.

Recognise the `linguist-documentation` and `linguist-detectable`
attributes in `.gitattributes` files, and use them in
`GetLanguageStats()` to make a decision whether to include a particular
file in the stats or not.
This allows one more control over which files in their repositories
contribute toward the language statistics, so that for a project that is
mostly documentation, the language stats can reflect that.
Fixes#1672.
