patch 8.2.2236: 'scroll' option can change when setting the statusline

Browse Source 
Problem:    'scroll' option can change when setting the statusline or tabline
            but the option context is not updated.
Solution:   Update the script context when the scroll option is changed as a
            side effect. (Christian Brabandt, closes #7533)
