patch 9.2.0178: DEC mode requests are sent even when not in raw mode

patch 9.2.0178: DEC mode requests are sent even when not in raw mode

Problem: Vim sends DEC mode query requests (DECRQM) regardless of the
terminal mode.
Solution: Only send DEC mode requests when cur_tmode is TMODE_RAW, but
e.g not for gui mode (Foxe Chen).

fixes: #19709
closes: #19710
