Add code editor setting dropdowns (#36534)

Adds three `<select>` controls on top right for indent style, indent
size, and line wrap to the code editor (`_edit`), diff patch editor
(`_diffpatch`) and git hook editor (`/settings/hooks/git/pre-receive`).

The git hooks editor is restyled to wrap the content in a box. Also
included is a bugfix for the git hooks editor where monaco was not
initialized correctly.
