[rocPRIM][hipCUB][rocThrust][rocRAND] CP Versioning and changelog updates for 7.2 release (#3331)

## Motivation

Changelog entries, internal version numbers, and rocPRIM/rocRAND
dependency release branches need to be updated for the 7.2 release.

## Technical Details

Updates the items mentioned above. Note that hipRAND has not noteworthy
changes for 7.2.

## Test Plan

Run a build, make sure there are no cmake errors. View the changelogs to
make sure there are no formatting errors.

## Test Result

No build issues.

+## rocPRIM 4.2.0 for ROCm 7.2
+
+### Added
+
+* Added missing benchmarks, such that every autotuned specialization is now benchmarked.
+* Added a new cmake option, `BENCHMARK_USE_AMDSMI`. It is set to `OFF` by default. When this option is set to `ON`, it lets benchmarks use AMD SMI to output more GPU statistics.
+* Added the first tested example program for `device_search`, which is linked in the documentation.
+* Added `apply_config_improvements.py`, which generates improved configs by taking the best specializations from old and new configs.
+  * Run the script with `--help` for usage instructions, and see `projects/rocprim/docs/concepts/tuning.rst` for documentation.
+* Kernel Tuner proof-of-concept.
+* Enhanced SPIR-V support and performance.
+  
+### Optimizations
+
+* Improved performance of `device_radix_sort` onesweep variant 
+
+### Resolved issues
+
+* Fixed the issue where `rocprim::device_scan_by_key` failed when performing an "in-place" inclusive scan by reusing "keys" as output, by adding a buffer to store the last keys of each block (excluding the last block). This fix only affects the specific case of reusing "keys" as output in an inclusive scan, and does not affect other cases.
+* Fixed benchmark build error on Windows.
+* Fixed offload compress build option.
+* Fixed `float_bit_mask` for `rocprim::half`. 
+* Fixed handling of undefined behaviour when `__builtin_clz`, `__builtin_ctz`, and similar builtins are called.
+* Fixed potential build error with `rocprim::detail::histogram_impl`.
+
+### Known issues
+
+* Potential hang with `rocprim::partition_threeway` with large input data sizes on later ROCm builds. A workaround is currently in place.

 ## rocPRIM 4.1.0 for ROCm 7.1
 
 ### Added
@@ -12,11 +41,7 @@ Full documentation for rocPRIM is available at [https://rocm.docs.amd.com/projec
 * Added a new cmake option, `BUILD_OFFLOAD_COMPRESS`. When rocPRIM is build with this option enabled, the `--offload-compress` switch is passed to the compiler. This causes the compiler to compress the binary that it generates. Compression can be useful in cases where you are compiling for a large number of targets, since this often results in a large binary. Without compression, in some cases, the generated binary may become so large symbols are placed out of range, resulting in linking errors. The new `BUILD_OFFLOAD_COMPRESS` option is set to `ON` by default.
 * Added a new CMake option `-DUSE_SYSTEM_LIB` to allow tests to be built from `ROCm` libraries provided by the system.
 * Added `rocprim::apply` which applies a function to a `rocprim::tuple`.

 * Fixed `device_select`, `device_merge`, and `device_merge_sort` not allocating the correct amount of virtual shared memory on the host.
 * Fixed the `->` operator for the `transform_iterator`, the `texture_cache_iterator` and the `arg_index_iterator`, by now returning a proxy pointer.
   * The `arg_index_iterator` also now only returns the internal iterator for the `->`.
