patch 8.2.4993: smart/C/lisp indenting is optionalv8.2.4993

Problem:    smart/C/lisp indenting is optional, which makes the code more
            complex, while it only reduces the executable size a bit.
Solution:   Graduate FEAT_CINDENT, FEAT_SMARTINDENT and FEAT_LISP.

 There are in fact four main methods available for indentation, each one
 overrides the previous if it is enabled, or non-empty for 'indentexpr':
 'autoindent'	uses the indent from the previous line.
