This patch provides TYPED_TEST and TYPED_TEST_F (similar in functionnality to gtest).
This is needed to extensively test building blocks for memory functions.

Example for TYPED_TEST_F:

  template <typename T> class LlvmLibcMyTestFixture : public testing::Test {};
  
  using Types = testing::TypeList<char, int, long>;
  
  TYPED_TEST_F(LlvmLibcMyTestFixture, Simple, Types) {
    EXPECT_LE(sizeof(ParamType), 8UL);
  }

Example for TYPED_TEST:

  using Types = testing::TypeList<char, int, long>;
  
  TYPED_TEST(LlvmLibcMyTest, Simple, Types) {
    EXPECT_LE(sizeof(ParamType), 8UL);
  }

Because we can't use RTTI and <typeinfo>, `TypeParam` is displayed as "UNSET" by default and the user can provide a readable name using the `REGISTER_TYPE_NAME` macro.

I noticed that Fuchsia is using its own testing framework. We can either add the same functionality to zxtest or disable them on Fuchsia. WDYT?
