patch 9.1.1398: completion: trunc does not follow Pmenu highlighting attributes

Problem:  When items are combined with user-defined highlight attributes
          (e.g., strikethrough), trunc inherits these attributes, making
          the text difficult to read.
Solution: trunc now uses the original Pmenu and PmenuSel highlight
          attributes (glepnir)

closes: #17340
