[CMake] Link TFormulaTests also against Vc if available

This is needed for the vectorization tests. Also, remove the
`BUILTINS Vc` arguments, that were used to declare dependencies in
builtins at the level of CMake targets. But this is not needed anymore,
as `Vc` in the `Vc_LIBRARIES` is a target itself now when using
`builtin_vc` (as of e147d36).
