The mm/vmscan.c file is too large, so separate the shrinker-related
code from it into a separate file. No functional changes.

A good cleanup, vmscan.c is so huge.
I'd like to introduce a new header in mm/ directory and contains those
declarations of functions (like this and other debug function in
shrinker_debug.c) since they are used internally across mm.
How about putting them in the mm/internal.h file?
Either is fine to me.
OK, will do in the next version.
Thanks.
