devel/cmake: add support for choosing BLAS/LAPACK .pc

This adds already upstreamed patches to FindBLAS.cmake and FindLAPACK.cmake
that enables our build infrastructure to better select which BLAS package
to locate in cmake-using builds via specifying a name for pkg-config
instead of hardcoded 'blas' or 'lapack'.

Remove with cmake-3.25.
