Allow conditional variants (#24858)
A common question from users has been how to model variants
that are new in new versions of a package, or variants that are
dependent on other variants. Our stock answer so far has been
an unsatisfying combination of "just have it do nothing in the old
version" and "tell Spack it conflicts".
This PR enables conditional variants, on any spec condition. The
syntax is straightforward, and matches that of previous features.
