mm/damon: move the implementation of damon_insert_region to damon.h
Usually, inline function is declared static since it should sit between
storage and type. And implement it in a header file if used by multiple
files.
And this change also fixes compile issue when backport damon to 5.10.
mm/damon/vaddr.c: In function `damon_va_evenly_split_region':
./include/linux/damon.h:425:13: error: inlining failed in call to `always_inline' `damon_insert_region': function body not available

mm/damon/vaddr.c:86:3: note: called from here
86 | damon_insert_region(n, r, next, t);
