@lynnllh Will dup the fd cause fd memory leak?

@lynnllh Will dup the fd cause fd memory leak?

1. In fact, when playing large files, AVPlayer is used for playback. After playback ends, the OH_AVPlayer_Release interface is called, which releases the file descriptor (fd) held by it. Therefore, under normal circumstances, playing large files will not cause FD leakage.
2. However, when playing small files, they are parsed into PCM streams for playback, and at this time, the FD handle is not released, causing leakage.
3. However, in reality, within the branch where audioFilePath[0]!= '/', fileUtils->getRawFileDescriptor is called. This method calls OH_ResourceManager_GetRawFileDescriptor64 to obtain the FD. This method also has a corresponding method OH_ResourceManager_ReleaseRawFileDescriptor64 that needs to be called to release the FD. However, this call is not made in the code, so FD leakage also occurs when playing small files. I will consider both scenarios together to see how to handle them appropriately.

Sorry, I rechecked the code and found that there is a close operation for FD in the destructor of AssetFD, so it should not cause FD leakage.
