runtime(doc): Improve command-line completion docs (#13331)

Browse Source 
* Improve command-line completion docs

Add more details about 'ignorecase' and its effect on cmdline
completion.

Make sure keys used in wildmenu are properly documented and linked in the
keys' documentation entries, and in `:h index` for proper
cross-referencing, as wildmenu popup is slightly different from
insert-mode popup menu.

* Fix docs typos
