Memory leak in StringPool

[minggo]

inline StringHandle StringPool<ThreadSafe>::doStringToHandle(const char *str) noexcept {
    const auto it = _stringToHandles.find(str);

    if (it == _stringToHandles.end()) {
        size_t const strLength = strlen(str) + 1;
        char *const  strCache  = new char[strLength];  // memory leak: create memory, but do't find anywhere to free the memory
        strcpy(strCache, str);
        StringHandle name(static_cast<StringHandle::IndexType>(_handleToStrings.size()), strCache);
        _handleToStrings.emplace_back(strCache);
        _stringToHandles.emplace(strCache, name);
        return name;
    }
    return it->second;
}

Currently, StringPool is used in FrameGraph. Maybe can use ccstd::string instead?

Oh, the memory is freed in destructor.
