SIRIUS package: add v6.3.2 + Python/MKL support (#12472)

* Add version 6.3.2 (which does not require patches like 6.1.5)
* Add +python variant to build Python bindings
* Option to build shared libraries does not exist for newer
  versions including 6.3.2
* Update 'libs' property (library names are different for newer
  versions)
* Add support to detect and build with MKL as blas provider
