Prior to libavif 1.1.0, `avifAlloc()` was infallible (it called
`abort()` on OOM conditions); thus, several API functions which used
`avifAlloc()` did not report failure. That changed as of libavif
1.0.0[1], so checking and handling failure conditions can now be done.
However, due to `avifAlloc()` being fallible as of libavif 1.1.0, this
error checking and handling is mandatory to avoid more serious issues.

Closes GH-16434.
Some AVIF image generators didn't include the PixelInformationProperty
(pixi), even though strictly speaking they should. In v0.9.2, libavif
began requiring this. Let's disable it so we can read those images too.
We also remove xfail from test on FreeBSD.
Closes GH-7253.
This backports avif support from upstream libgd into bundled libgd
and exposes the functionality through new imagecreatefromavif()
and imageavif() functions.
Closes GH-7026.
