* Add C conversions of the CBLAS tests for NOFORTRAN=1 builds

* Enable CTEST without Fortran and fix passing of BUILD_vartype options to exports/gensymbol

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

* Use linker response files and a custom link command to get around ARG_MAX limitations on OSX
* Reconfigure a redundant job on Azure to test shared library builds with CMAKE and DYNAMIC_ARCH on OSX

When both BUILD_SHARED_LIBS and BUILD_STATIC_LIBS are enabled,
cmake export both of them to OpenBLASTargets under tha same name `OpenBLAS::OpenBLAS`
which leads to fatal error about OpenBLAS::OpenBLAS being both static and shared target.
This change makes cmake export only the shared library in that case.
There is another solution to treat them as components,
but I am afraid that will make it backward incompatible.

Add some extra lines and indentations.

Generating the pkg-config file does not actually depend on pkg-config being available.

* make building the bfloat16 BLAS functions conditional on BUILD_HALF

* pass the BUILD_HALF option to gensymbol

* Pass BUILD_HALF as a compiler define for dynamic_arch builds

target_link_libraries does not work here according to issue 2472
