feat(test/gtest): add map type support for AssertNI/AssertIN

[ansionfor]

AssertNI/AssertIN func support map type

func TestAssertIN_Map(t *testing.T) {
	gtest.C(t, func(t *gtest.T) {
		t.AssertIN("k1", map[string]string{"k1": "v1", "k2": "v2"})
		t.AssertIN(1, map[int64]string{1: "v1", 2: "v2"})
		t.AssertIN([]string{"k1", "k2"}, map[string]string{"k1": "v1", "k2": "v2"})
	})
}

func TestAssertNI_Map(t *testing.T) {
	gtest.C(t, func(t *gtest.T) {
		t.AssertNI("k3", map[string]string{"k1": "v1", "k2": "v2"})
		t.AssertNI(3, map[int64]string{1: "v1", 2: "v2"})
		t.AssertNI([]string{"k3", "k4"}, map[string]string{"k1": "v1", "k2": "v2"})
	})
}
