Enable `SimpleArray::matmul_veclib()` on Linux and Windows using openblas

[ThreeMonth03]

In order to create new baseline for matrix multiplication operation with third-party library, we deal with issue #789 by pull request #800.

However, new testcases created in pr #800 shound be refactored (see comment), which could be simultaneously adjusted when extending SimpleArray::matmul_veclib() on different platforms.

Therefore, the following lists are follow-up tasks:

• Add OpenBLAS support to SimpleArray::matmul_veclib() on Linux and windows
• Refactor corresponding unittests related to SimpleArray::matmul_veclib()

Consider to add matmul to the LAPACK abstraction layer cpp/modmesh/linalg/lapack_compat.hpp added for issue #823 (PR #806 / issue #804). To make the LAPACK abstraction layer work for both buffer/ and linalg/ modules, it needs to be factored outside the current location in cpp/modmesh/linalg/.
