Merge Close release 1.8.0 on develop, now preparing 1.9.0

Release 1.8.0 to develop. The Ginkgo team is proud to announce the new Ginkgo minor release 1.8.0. This release brings new features such as: - A brand new file-based configuration for Ginkgo objects: you can now construct Ginkgo objects (solvers, preconditioners, ...) from a JSON configuration file. This simplifies interfacing to Ginkgo as well as exploring different settings to solve a problem. - Expand the batched feature set with: the Batched CSR Matrix format, batched CG solver, batched (Block-)Jacobi preconditioner, usage example and other features such as scaling, - New Distributed Multigrid and the PGM coarsening method, - New CUDA and HIP kernels for Reverse Cuthill McKee (RCM) reordering - Better Ginkgo and Kokkos interaction thanks to a mapping from simple Ginkgo types to native Kokkos types and more! See [the Changelog](./CHANGELOG.md) for more information. Related PR: ginkgo-project#1621

+## Version 1.8.0
+
+The Ginkgo team is proud to announce the new Ginkgo minor release 1.8.0. This
+release brings new features such as:
+- A brand new file-based configuration for Ginkgo objects: you can now construct
+  Ginkgo objects (solvers, preconditioners, ...) from a JSON configuration file.
+  This simplifies interfacing to Ginkgo as well as exploring different settings
+  to solve a problem.
+- Expand the batched feature set with: the Batched CSR Matrix format, batched CG
+  solver, batched (Block-)Jacobi preconditioner, usage example and other
+  features such as scaling,
+- New Distributed Multigrid and the PGM coarsening method,
+- New CUDA and HIP kernels for Reverse Cuthill McKee (RCM) reordering
+- Better Ginkgo and Kokkos interaction thanks to a mapping from simple Ginkgo
+  types to native Kokkos types
+
+and more!
+

+### Version support changes
++ The Ginkgo license header now uses the SPDX format. [#1404](https://github.com/ginkgo-project/ginkgo/pull/1404)
++ Ginkgo changes the oneapi support to 2023.1+ [#1396](https://github.com/ginkgo-project/ginkgo/pull/1396)
++ Ginkgo's HIP backend now requires CMake 3.21 [#1334](https://github.com/ginkgo-project/ginkgo/pull/1334)
+
+### Interface changes
+
++ The `gko::dim` single-parameter constructor is now `explicit` to avoid accidental conversion from integers [#1474](https://github.com/ginkgo-project/ginkgo/pull/1474)
++ The CMake option `GINKGO_BUILD_HWLOC` is now set to `OFF` by default, and if it is set to `ON`, then `HWLOC` is required to be available [#1513](https://github.com/ginkgo-project/ginkgo/pull/1513).
+
+### Behavior changes
+
++ `gko::write_raw` now defaults to writing sparse output unless otherwise specified [#1533](https://github.com/ginkgo-project/ginkgo/pull/1533)
++ Ginkgo now adheres to the `--prefix` option for `cmake --install`, instead of overwriting it [#1534](https://github.com/ginkgo-project/ginkgo/pull/1534)
+
+### Deprecations
+
++ `array::get_num_elems()` has been renamed to `get_size()` [#1400](https://github.com/ginkgo-project/ginkgo/pull/1400)
++ `matrix_data::ensure_row_major_order()` has been renamed to `sort_row_major()` [#1400](https://github.com/ginkgo-project/ginkgo/pull/1400)
++ `device_matrix_data::get_num_elems()` has been renamed to `get_num_stored_elements()` [#1400](https://github.com/ginkgo-project/ginkgo/pull/1400)
++ The CMake parameter `GINKGO_COMPILER_FLAGS` has been superseded by `CMAKE_CXX_FLAGS`, and `GINKGO_CUDA_COMPILER_FLAGS` has been superseded by `CMAKE_CUDA_FLAGS` [#1535](https://github.com/ginkgo-project/ginkgo/pull/1535)
++ The `std::initializer_list` overloads of matrix `create` methods and constructors are deprecated in favor of explicit `array` parameters [#1433](https://github.com/ginkgo-project/ginkgo/pull/1433)
+
+### Summary of previous deprecations
++ The `device_reset` parameter of CUDA and HIP executors no longer has an effect, and its `allocation_mode` parameters have been deprecated in favor of the `Allocator` interface.
++ The CMake parameter `GINKGO_BUILD_DPCPP` has been deprecated in favor of `GINKGO_BUILD_SYCL`.
++ The `gko::reorder::Rcm` interface has been deprecated in favor of `gko::experimental::reorder::Rcm` based on `Permutation`.
++ The Permutation class' `permute_mask` functionality.
++ Multiple functions with typos (`set_complex_subpsace()`, range functions such as `conj_operaton` etc).
++ `gko::lend()` is not necessary anymore.
++ The classes `RelativeResidualNorm` and `AbsoluteResidualNorm` are deprecated in favor of `ResidualNorm`.
++ The class `AmgxPgm` is deprecated in favor of `Pgm`.
++ Default constructors for the CSR `load_balance` and `automatical` strategies
++ The PolymorphicObject's move-semantic `copy_from` variant
++ The templated `SolverBase` class.
++ The class `MachineTopology` is deprecated in favor of `machine_topology`.
++ Logger constructors and create functions with the `executor` parameter.
++ The virtual, protected, Dense functions `compute_norm1_impl`, `add_scaled_impl`, etc.
++ Logger events for solvers and criterion without the additional `implicit_tau_sq` parameter.
++ The global `gko::solver::default_krylov_dim`, use instead `gko::solver::gmres_default_krylov_dim`.
+
+### Added features

++ The HIP backend now supports complex number operations for sparse matrices based on hipSPARSE [#1538](https://github.com/ginkgo-project/ginkgo/pull/1538)

++ The Multigrid solver generated from `distributed::Matrix` will use a global scalar Jacobi smoother and a GMRES solver as coarse grid solver [#1612](https://github.com/ginkgo-project/ginkgo/pull/1612)
+
+### Fixes
+
++ Compilation with libc++ was fixed [#1463](https://github.com/ginkgo-project/ginkgo/pull/1463)

++ Fix the interaction of `ProfilerHook::create(_nested)_summary`, executors and GPU timers, which lead to the summary not being printed [#1509](https://github.com/ginkgo-project/ginkgo/pull/1509)
++ Fix compilation in environments where `CPATH` contains the current working directory [#1531](https://github.com/ginkgo-project/ginkgo/pull/1531)
