Add distinction between RGB and RGBA native texture video frames and resources

Add distinction between RGB and RGBA native texture video frame and resources

Currently it's impossible to place a NATIVE_TEXTURE VideoFrame into an
overlay, because:
* NATIVE_TEXTURE VideoFrame turns into RGB_RESOURCE in
  VideoResourceUpdater
* RGB_RESOURCE always sets premultipled_alpha flag on its
  TextureDrawQuad (see VideoLayerImpl::AppendQuads)
* OverlayStrategyCommon rejects quads with premultiplied alpha

PTAL, merge with https://codereview.chromium.org/1117423002 was nontrivial:
* Removed the alpha flag as that change already added a texture format field
that can hold this info
* Reworded CL description accordingly
