TST, MAINT: bump to OpenBLAS 0.3.7 stable

* for those cases where our CI uses an OpenBLAS backend
for testing it has now been updated to use v0.3.7 stable release
instead of a commit hash on the development branch preceding that
release

* the pre-built OpenBLAS binaries are pulled in from either the
MacPython ecosystem (most architectures) or from a custom build
script for ARMv8 and ppc64le architectures used on gcc compile farm machines
(documented in openblas_support module)
