Support for AVIF in PHP8.1RC3

[mondrake]

Describe the feature
PHP 8.1 bundled GD supports the AVIF file format, php/php-src#7026.

However the 8.1RC3 executable loaded by the plugin does not seem to have been compiled with AVIF support.

Is it possible to support it?

Version

• I have checked releases, and the feature is missing in the latest patch version of v2.

Underlying issue
AVIF image file support

Describe alternatives

Additional context

Are you willing to submit a PR?
Not really my field.

libavif package is only available for Ubuntu 21.04/Debian 11 and above, so most likely ppa:ondrej/php will add it for their packaging or update libgd to version which adds avif support. Then I will add support for it here.
