  Log Message:
  -----------
  [CIR] Implement array delete for destructed types (#186248)

This extends the cir.delete_array lowering code to introduce a loop that
calls destructors when the array being deleted represents a destructed
type. The lowering introduces the destructors by way of a cir.array.dtor
operation, which is further expanded during LoweringPrepare. This also
required updating the cir.array.dtor operation to accept a raw pointer
to the element type and a value representing the number of elements to
be destructed.

This does not yet handle the possibility of destructors throwing
exceptions.
