57d9788d1b configure: simplify libwebp checks 
The libwebpmux pkg-config file already has an explicit dependecy on libwebp >= 0.2.0.
Also remove the warning and silently disable the anim encoder when libwebpmux is not new enough.
This is more in line with other library components, like libvpx-vp9

02cf59f3a6 WebP encoder: use WebPAnimEncoder API when available. 
WebPAnimEncoder API is a combination of encoder (WebPEncoder) and muxer
(WebPMux). It performs several optimizations to make it more efficient
than the combination of WebPEncode() and native ffmpeg muxer.

When WebPAnimEncoder API is used:
- In the encoder layer: we use WebPAnimEncoderAdd() instead of
  WebPEncode().
- The muxer layer: works like a raw muxer.

On the other hand, when WebPAnimEncoder API isn't available, the old code is
used as it is:
- In the codec layer: WebPEncode is used to encode each frame
- In the muxer layer:  ffmpeg muxer is used
