Add memory layout relayout functions

[wdeconinck]

Description

This pull request introduces several significant improvements and additions to the build system, device abstraction layer, and testing infrastructure. The main changes are the addition of new device property abstractions for the dummy backend, integration of new relayout utilities, and the introduction of a comprehensive benchmarking executable and smoke tests for relayout functionality.

Relayout Utilities Integration:

• Added new relayout utility source files (relayout.cc, relayout.h, relayout_on_host.cc, relayout_on_device.hic) to the build system in src/atlas/CMakeLists.txt, improving support for data layout transformations on both host and device. [1] [2]

Benchmarking and Testing Infrastructure:

• Introduced a new executable atlas-benchmark-relayout and an extensive set of smoke tests to cover various relayout scenarios, including rank-2/3/4 data, loop order variants, memcpy toggles, and device execution. This enhances test coverage and performance benchmarking capabilities.

Configuration Macros:

• Improved macro definitions in defines.h.in to ensure bounds checking macros are only defined if not already present, avoiding redefinition and improving configurability.

Device Abstraction and Runtime Enhancements:

• Added a new dummyDeviceProp_t struct in hic_dummy_runtime.h to represent device properties for the dummy backend, and registered new dummy device functions such as GetDevice and GetDeviceProperties. [1] [2]
• Updated the device property type alias DeviceProp_t in hic_runtime.h to be backend-specific, supporting CUDA, HIP, and Dummy backends. Also registered new device-related functions in the HIC interface. [1] [2]
