patch 9.1.0174: 'cursorline' and 'wincolor' hl missing with conceal and wrap

Problem:  'cursorline' and 'wincolor' highlight missing with concealed and
          wrapped lines.
Solution: Apply 'cursorline' and 'wincolor' highlight to boguscols.
          (zeertzjq)

Since 'cursorline' and 'wincolor' highlight apply after the end of the
line, it is more consistent to have them also apply to boguscols.

Assigning MAXCOL to values in ScreenCols[] make mouse click behave the
same with 'cursorline' and 'nocursorline', but such behavior may be
incorrect, as it puts the cursor on the next screen line.  That may be
fixed in a future PR.
