mm/damon/sysfs: split out schemes directory implementation to separate file 

mainline inclusion
from mainline-v6.2-rc6
commit c8e7b4d0
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I6MRUG

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c8e7b4d0ba348a8ef14956a80c780f152f433764

--------------------------------

DAMON sysfs interface for 'schemes' directory is implemented using about
one thousand lines of code.  It has no strong dependency with other
parts of its file, so split it out to another file for better code
management.
