Using `OpenMP::OpenMP_LANG` targets for CMake is less error-prone than
passing the compiler and linker flags manually. Furthermore, it allows
the user to customize those flags by setting `OpenMP_LANG_FLAGS`,
`OpenMP_LANG_LIB_NAMES`, and `OpenMP_omp_LIBRARY`.

* Added ARMV9SME target
* Added SGEMM_DIRECT kernel based on SME1

fixes 668f48f4fc

* Use CMAKE_C_COMPILER_VERSION throughout

`-exhaustive-register-search` is an LLVM code generation flag that shouldn't be passed directly to clang compiler.

* Filter out FFLAGS that flang-new from LLVM18 no longer supports

* Add support for the Cray Fortran compiler

* Fix f2c-like support functions to compile with MSVC, and
re-enable C_LAPACK for MSVC in CMAKE

* Add MSVC&flang build to Azure CI in order to check C_LAPACK correctness

* Add C equivalents of the Fortran routines from Reference-LAPACK as fallbacks, and C_LAPACK variable to trigger their use

If no customized GEMM_SMALL_M_PERMIT kernel defined, it will just by pass to normal path.

Fix Cooperlake/DYNAMIC_ARCH builds with clang on Windows
