Various fixes for frame capture

1. Use contextId as identifier to separate captures for different GL context. 2. Fix write string params. In order to keep consistent between replay and capture, changes have been made to store C style string (with '\0' suffix) for string param capture, which breaks cpp frame capture. This change fixes it. 3. On Android device, it use a custom path to save captures and it breaks the loadBinaryData(). Here differentiate file name and file path to fix it.
