Preparation for building the new collapse engine in its own file.  The
engine and khugepaged.c need to agree on what a collapse result is and
what state a scan carries.

Move enum scan_result and struct collapse_control into a new
mm/collapse.h.

No functional change intended.

Any change that introduces a new file should in the same change update
MAINTAINERS (in the THP section to which this belongs :)

Will do.
