read_and_insert_process_output: Insert before markers

* src/insdel.c (adjust_markers_for_insert): Make non-static.

* src/lisp.h: Add declaration for it.

* src/process.c (read_and_insert_process_output): Use it here.
And also call insert_1_both with BEFORE_MARKERS=t, for
compatibility with internal-default-process-filter (bug#66020).
