bug#45200: [PATCH] Force Glibc to free the memory freed

What I meant was a function say 'garbage-collect-and-trim' that would do
the same as ‘garbage-collect’ but in addition run 'malloc_trim(0)' so
the person that earlier used

(setq gc-cons-threshold (eval-when-compile (* 1024 1024 1024)))
(run-with-idle-timer 2 t (lambda () (garbage-collect)))

would now run

(setq gc-cons-threshold (eval-when-compile (* 1024 1024 1024)))
(run-with-idle-timer 2 t (lambda () (garbage-collect-and-trim)))

instead.
