* 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

long's in windows are 4 bytes (MSVS, intel compilers). Use int64_t and int32_t
to ensure 8 byte integers for ILP interface.
