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

ending up back to what was typed. If the first match is not what you wanted,
you can use <S-Tab> or CTRL-P to go straight back to what you typed.
The 'wildignorecase' option can be set to ignore case in filenames.
The 'wildmenu' option can be set to show the matches just above the command
line.
The 'wildoptions' option provides additional configuration to use a popup menu
for 'wildmenu', and to use fuzzy matching.
The 'wildignorecase' option can be set to ignore case in filenames. For
completing other texts (e.g. command names), the 'ignorecase' option is used
instead (fuzzy matching always ignores case, however).
If you like tcsh's autolist completion, you can use this mapping:
:cnoremap X <C-L><C-D>
(Where X is the command key to use, <C-L> is CTRL-L and <C-D> is CTRL-D)
