We had made services.cc depend on //brave/utility via a chromium_src
override, but that caused a dependency cycle because //brave/utility
also depends on //chrome/utility (e.g. extend some upstream classes),
causing a gn check error.
To fix this, we can follow the pattern used in other places and make
upstream's //chrome/utility directly include the files from Brave that
it needs, and replace the oneliner patch to //chrome/utility/BUILD.gn
with one that would simply include those sources, instead of having it
depend on //brave/utility.
Last, we also add a missing dep on //brave/common/importer:importer
to avoid another gn check failure due to having some files from that
target included from brave_external_process_importer_bridge.h.
