  Log Message:
  -----------
  [VPlan] Introduce VPWidenIntrinsicRecipe to separate from libcall. (#110486)

This patch splits off intrinsic hanlding to a new
VPWidenIntrinsicRecipe. VPWidenIntrinsicRecipes only need access to the
intrinsic ID to widen and the scalar result type (in case the intrinsic
is overloaded on the result type). It does not need access to an
underlying IR call instruction or function.

This means VPWidenIntrinsicRecipe can be created easily without access
to underlying IR.
