bug#36361: 'hl-line-range-function' as list of choice

[Sebastian Urban]

Because 'hl-line-mode' highlight logical line instead of screen line
when 'visual-line-mode' is active, and for example 'C-a' and 'C-e'
change behaviour, some people want 'hl-line-mode' to change the
behaviour as well.  They usually use 'hl-line-range-function' to
define how it should highlight, but... cannot it be made simpler?
Like by making 'hl-line-range-function' a list of choice:
- nil for default behaviour,
- "Screen line" to change to screen line,
- "Function" for user to write what he wants.
I'm writing this from perspective of "Customize" menu.
