Add missing Thrust includes

[bdice]

Description

This PR cleans up some #includes for Thrust. This is meant to help ease the transition to Thrust 1.17 when that is updated in rapids-cmake.

Context

I opened a PR rapidsai/cudf#10489 that updates cuDF to Thrust 1.16. Notably, version 1.16 of Thrust reduced the number of internal header inclusions:

#1572 Removed several unnecessary header includes. Downstream projects may need to update their includes if they were relying on this behavior.

I spoke with @robertmaynard and he recommended making similar changes to clean up includes ("include what we use," in essence) to make sure we have compatibility with future versions of Thrust across all RAPIDS libraries.

This changeset also makes it more obvious where cugraph depends on thrust/detail headers.

From the CI output, it appears that Thrust 1.15.0 is being used.

I also built this branch locally with rapids-compose's build-cugraph-cpp command. I see:

-- CPM: adding package libcudacxx@1.7.0 (1.7.0)
-- CPM: adding package cuco@0.0 (0ca860b824f5dc22cf8a41f09912e62e11f07d82)
-- CPM: cuco: adding package Thrust@1.12.0 (1.12.0)
-- Found Thrust: /home/bdice/rapids1/cugraph/cpp/build/cuda-11.7.0/thrust-includes/release/_deps/thrust-src/thrust/cmake/thrust-config.cmake (found version "1.17.0.0")
-- Found CUB: /home/bdice/rapids1/cugraph/cpp/build/cuda-11.7.0/thrust-includes/release/_deps/thrust-src/dependencies/cub/cub/cmake/cub-config.cmake (found suitable version "1.17.0.0", minimum required is "1.17.0.0")
-- CPM: adding package raft@22.08.00 (branch-22.08)
-- Found OpenMP_C: -fopenmp (found version "4.5")
-- Found OpenMP_CXX: -fopenmp (found version "4.5")
CMake Warning at build/cuda-11.7.0/thrust-includes/release/cmake/CPM_0.35.0.cmake:286 (message):
  CPM: raft: requires a newer version of Thrust (1.17.0) than currently
  included (1.12.0).

It looks like this commit of cuco is using CPM to include an older Thrust 1.12.0 version, which happens before my manual versions.json sets Thrust 1.17.0. This behavior is described in the rapids-cmake docs as "first to record, wins."

I pushed a commit 0ba6551 to force using 1.17.0 by including it before all other packages that also depend on Thrust (cuco, for instance). We'll see if that gets used by the CI this time. I was unable to test locally due to an error caused by rapids_find_package(cugraph-ops). I don't know how this package is supposed to be found...

This is blocked until raft is upgraded: rapidsai/raft#678

(compiling CMakeFiles/cugraph.dir/src/linear_assignment/hungarian.cu.o)
$PREFIX/include/raft/lap/lap.cuh(182): error: namespace "thrust" has no member "device"

rerun tests

[bdice]

Maybe this needs to wait until a new nightly package of libraft-headers is generated, and then re-run.

[bdice]

This is now blocked by rapidsai/cuhornet#57.

Looks like the build completed for 3fd8e6a, but there's some issue related to finding a libcudf that has an older CUB. I'm not sure if we need to debug this and override things. I think we can probably move forward without debugging that issue, since the build didn't fail with Thrust inclusion problems and it's just an issue of my version override not matching the rest of RAPIDS. I reverted my CMake changes overriding the Thrust version in 9d33fce, and I think this should be ready to review/merge.

Error from the previous build:

CMake Error at /workspace/.conda-bld/.../include/libcudf/Thrust/thrust/cmake/thrust-config.cmake:218 (message):
The version of CUB found by CMake is not compatible with this release of
Thrust.  CUB is now included in the CUDA Toolkit, so you no longer need to
use your own checkout of CUB.  Pass IGNORE_CUB_VERSION_CHECK to
thrust_create_target to ignore.  (CUB 1.17.0.0, Thrust 1.15.0.0).
