TODO: currently cpp/test/neighbors/ann_ivf_pq/test_float_uint32_t.cu is commented out to initially save CI time (this file takes a long time to build). Once CI is passing once I will uncomment it.
Description
This uses the IncludeCategories settings in .clang-format to automate include ordering and grouping and to make include ordering more consistent with the rest of RAPIDS. For discussion, see rapidsai/cudf#15063. This PR uses a similar set of header grouping categories used in that PR, adapted for RAFT.
The header reordering in this PR uncovered one place where
#include <cutlass/layout/pitch_linear.h>
was missing fromraft/cpp/include/raft/distance/detail/./pairwise_distance_epilogue_elementwise.h
, so I also added that include.One purpose of this is to make it easier to automate injection of a header change with an upcoming RMM refactoring (and in the future).
Closes #2193
