Swap out base/stl_util.h for base/containers/contains.h.

Files that only use base::Contains() and no other base/stl_util.h helper
can replace base/stl_util.h with base/containers/contains.h.

Use grep to find all the files that include base/stl_util.h. Then filter
out the ones that need base/stl_util.h by running "grep -L base::func"
where "func" is a function that base/stl_util.h provides. For the
remaining files, grep for ones that use base::Contains(), and do search
and replace for stl_util.h. Take the resulting CL and run clang format.
