fix(decor): highlight without 'hl_eol' bleeds into wrap gaps #41160

Problem:
'linebreak' filler and 'breakindent'/'showbreak' padding are screen
cells with no buffer character behind them, yet a decoration draws over
them whether or not it asked to cover such cells. A highlight bounded to
its text then paints a tail out to the edge of the row, most visible on
inline code spans from plugins. That same highlight already leaves the
cells past the end of a line alone, so it treats identical cells two
different ways.

Solution:
Only a decoration with 'hl_eol' draws the gaps, which is what the flag
already means at the end of a line. A full-width background such as a
fenced code block sets it and still covers them. Classic :syntax has no
such flag and is unchanged.
