patch 9.2.0755: 'autocomplete' behaves inconsistently when recording

patch 9.2.0755: 'autocomplete' behaves inconsistently when recording

Problem: If 'autocompletedelay' is non-zero, 'autocomplete' doesn't
work when recording a register (after 9.2.0750).
Solution: Still produce K_COMPLETE_DELAY when recording a register, and
drop it in gotchars_add_byte() instead (zeertzjq).

This patch only changes the behavior when recording a register.
Replaying a register with 'autocomplete' still doesn't fully work
regardless of 'autocompletedelay', as 'autocomplete' isn't triggered
when there is pending input.

closes: #20675
