Don't ignore restriction in indent-region-line-by-line

* lisp/indent.el (indent-according-to-mode): Don't widen if the new
optional argument is non-nil.
(indent-region): Explicitly widen before calling
indent-region-line-by-line.
(indent-region-line-by-line): Don't widen (bug#51892).

Emacs convention is that low-level functions should respect restriction
so that their callers can set restriction according to their needs. For
example, 'c-indent-region' is a lower-level function which respects the
current restriction and 'indent-region' is a higher-level user command
which sets the restriction for lower-level functions, it calls
"(widen)".

'indent-region-line-by-line' is a low-level function on a similar level
as 'c-indent-region'. This patch makes it respect the current
restriction instead of having it call "(widen)".
