Add MediaFoundation AAC encoder element. Before Windows 10, mono and stereo channels were supported audio channels configuration by AAC encoder MFT. However, on Windows 10, 5.1 channels support was introduced. To expose correct range of support format by this element whatever the OS version is, this element will enumerate all the supported format by the AAC encoder MFT and then will configure sink/src templates while plugin init.
