RFR: 8277309: Add support for H.265/HEVC to HTTP Live Streaming [v3]

[Alexander Matveev]

> - Added support for fragmented MP4 with HEVC/H.265, H.264 and AAC. 
>  - Added support for elementary AAC streams without any container for audio only streams.
>  - Added "aacparse" plugin from GStreamer. Required on Linux, since decoder cannot handle AAC elementary streams directly. DirectShow decoder works without it.
>  - DirectShow H.264 decoder on Windows and H.265/H.264 decoder on Linux will be reloaded when fMP4 stream changes resolution. Dynamic format change did not worked for these streams on Windows and Linux.
