Upgrade libwebp to v1.2.3

This upgrades `libwebp` (a subdependency of `YYImage`) from v1.0.2 to its
latest version, v1.2.3.

As of this writing, the [libwebp pod does not have v1.2.3][0], so I
modified [the v1.2.1 podspec][1] and vendored it into the project. You
may wish to [compare the v1.2.1 podspec with my version][2]. In the long
term, I will try to get this change submitted upstream.

I tested this with a variety of stickers (usually sent as WebP), [WebP's
alpha test images][2], and [a test WebP image from the Desktop app][3].
