auxdisplay: linedisp: add num_chars sysfs attribute
Add a read-only 'num_chars' sysfs attribute to report display digit count.
The num_chars attribute provides essential capability information to
userspace applications that need to know display dimensions before writing
messages, complementing the existing message and scroll controls.
No functional changes to existing behavior.
