Allow declaring possible values for variants with an associated condition. If the variant takes one of those values, the condition is imposed as a further constraint. The idea of this PR is to implement part of the mechanisms needed for modeling [packages with multiple build-systems]( https://github.com/spack/seps/pull/3). After this PR the build-system directive can be implemented as: ```python variant( 'build-system', default='cmake', values=( 'autotools', conditional('cmake', when='@X.Y:') ), description='...', ) ``` Modifications: - [x] Allow conditional possible values in variants - [x] Add a unit-test for the feature - [x] Add documentation
