修复测试用例

目前测试工具已加入 3rdparty, 基本的构建路径已修改。
一些用例编译通过。
还有一些用例编译报错：

```
D:\Develop\openharmony\histreamer\histreamer_dev\histreamer\tests\ut\TestBitReader.cpp:46:40: error: no matching function for call to 'OHOS::Media::Plugin::BitReader::ReadBits(int, int&)'
     EXPECT_EQ(bitReader.ReadBits(4, val), true);
D:/Develop/openharmony/histreamer/histreamer_dev/histreamer/engine/plugin/plugins/ffmpeg_adapter/utils/bit_reader.h:47:10: note:   template argument deduction/substitution failed:
D:/Develop/openharmony/histreamer/histreamer_dev/histreamer/engine/plugin/plugins/ffmpeg_adapter/utils/bit_reader.h:46:93: error: no type named 'type' in 'struct std::enable_if<false, bool>'
     template <typename T, typename std::enable_if<std::is_unsigned<T>::value, bool>::type = true>
                                                                                             ^~~~
```
对应的代码：

```
    template <typename T, typename std::enable_if<std::is_unsigned<T>::value, bool>::type = true>
    bool ReadBits(uint8_t bits, T& val)
    {...}
```
