  -----------
  [flang][OpenMP] Lowering support for declare variant. (#206988)

Add lowering support for OpenMP DECLARE VARIANT. Each directive is
recorded on its base procedure during the structure checks. During call
lowering, best variant is picked based on recorded selecter and context.

Note: this PR does not include module-file support for DECLARE VARIANT,
so cross-module variant resolution is not yet available; it will be
added in a follow-up PR.
