Use libyuv::ConvertToI420 for all color formats in video capture on WIN

Reland https://codereview.chromium.org/116573005/ with fix for android_aosp build.

Since libyuv has added support for image flipping (vertically) with negative
src_height as indicator, we'd converge all color formats into one code path.
And libyuv provides better performance.
