Make the "vpx" flag global, as it is used semi-consistently across
a number of packages to enable VP8/VP9 decoding (and/or encoding),
using media-libs/libvpx. Remove the redundant descriptions where they
don't add helpful information.

This was originally proposed in 2010, but was not followed through: https://archives.gentoo.org/gentoo-dev/201007311337.40902.hanno@gentoo.org/
