hipTensor 2.2.0 for ROCm 7.2.0

Added

• Added software-managed plan cache support.
• Added hiptensorHandleWritePlanCacheToFile to write the plan cache of a hipTensor handle to a file.
• Added hiptensorHandleReadPlanCacheFromFile to read a plan cache from a file into a hipTensor handle.
• Added simple_contraction_plan_cache to demonstrate plan cache usages.
• Added plan_cache_test to test the plan cache across various tensor ranks.
• Added C API headers to enable compatibility with C programs.
• Added a CMake function to allow projects to query architecture support.

Changed

• Updated C++ standard from C++17 to C++20.
• Include files hiptensor/hiptensor.hpp and hiptensor/hiptensor_types.hpp are now deprecated. Use hiptensor/hiptensor.h and hiptensor/hiptensor_types.h instead.
• Converted include guards from #ifndef/#define/#endif to #pragma once.

Resolved issues

• Removed large tensor sizes causing problem in benchmarks.
