This patch extends the capabilities of WMFMediaDataEncoder to support the encoding of RGBA images. It achieves this by integrating a new function, ConvertToNV12, which efficiently converts RGB* images to the NV12 format, making the encoding of RGBA content on Windows possible. Depends on D208168 Differential Revision: https://phabricator.services.mozilla.com/D207899
