Fix T93856: VP9 lossless render missing alpha

Browse Source 
Since 0ea0ccc4ff, `AV_PIX_FMT_YUV444P` pixel format was used for
lossless renders, which did override `AV_PIX_FMT_YUVA420P` format when
"RGBA" output is chosen. VP9 encoder doesn't seem to support
`AV_PIX_FMT_YUVA444P` pixel format, so use `AV_PIX_FMT_YUVA420P` for
lossless RGBA ouput instead.
