concretizer: treat conditional providers correctly (#20086)
refers #20040

This modification emits rules like:

provides_virtual("netlib-lapack","blas") :- variant_value("netlib-lapack","external-blas","False").

for packages that provide virtual dependencies conditionally instead
of a fact that doesn't account for the condition.
