  [flang][OpenMP] Support lowering of metadirective (part 2)

Lower non-constant user={condition(expr)} selectors in metadirectives
to a fir.if/else chain.

Only statically applicable when-clauses participate in dynamic
selection. Dynamic conditions are evaluated at runtime in declaration
order, with the best static match, an explicit otherwise/default
clause, or implicit nothing as the final fallback.

This patch is part of the feature work for #188820.

Assisted with copilot and GPT-5.4
