  [libc] Extends the testing framework to support typed test

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);
}
```

`ParamType` is displayed as fully qualified canonical type which can be difficult to read, the user can provide a more readable name by using the `REGISTER_TYPE_NAME` macro.
