Improve blis and numpy build dependencies (#6455)

* Fix blis build dependencies

* Add blis with python_version constraints to pyproject.toml
* Add blis to setup_requires

* Remove --only-binary from CI

* Reduce number of builds to speed up CI

* Add hack to install wheel for python 3.5 in linux

* Remove os spec from CI

* Remove detailed numpy build constraints

* Remove detailed numpy build constraints from `pyproject.toml` because
  it is too difficult to maintain for many architectures
  * These constraints are more a reflection of what is available on
    pypi as binary wheels rather than any real build requirements that
    it is necessary for users to follow when building from source
  * Users building their own binary packages will need to enforce the
    constraints that make sense in their environments, e.g., the `conda`
    compatible numpy pins

* Keep the build constraints in `build-constraints.txt` for use with our
  builds
  * Our builds with wheelwright are built against the earliest
    compatible binary versions of numpy on pypi
  * These constraints are documented within the distribution

* Revert "Remove os spec from CI"

This reverts commit 7489476688.
