+Bug 1515641 - Turn --enable-av1 around. r=nalexander
+
+AV1 is actually enabled everywhere by default (except 32-bits Windows
+when building with MSVC), so let's make the option --disable-av1 rather
+than --enable-av1. Also, since AV1 is backed by both libaom and
+libdav1d, remove mentions to libaom.
