What problem does this PR solve?

Issue Number: ref #35240

Problem Summary: planner: remove old useless interfaces about cost model

What is changed and how it works?

No logical change, just refactor, remove some old and useless cost interfaces:

PhysicalPlan.Cost()
PhysicalPlan.SetCost()
task.cost()
task.addcost()

Now, all logic related to the cost model is in plan_cost.go.

I wrote a UT locally to compare costs of all queries in plan_cost_test.go on this PR and Master branch, no diff was found:

func TestPlanCost(t *testing.T) {
	store := testkit.CreateMockStore(t)
	tk := testkit.NewTestKit(t, store)

	tk.MustExec("use test")
	tk.MustExec(`create table t (a int primary key, b int, c int, d int, k int, key b(b), key cd(c, d), unique key(k))`)
