[5.0] AVIF support for media manager

[wilsonge]

Allow media manager to have AVIF files uploaded and rendered

Summary of Changes

AVIF is an alternative to webp in some circumstances (see https://www.smashingmagazine.com/2021/09/modern-image-formats-avif-webp/ for more info).

I've deliberately chosen to not add this to a SQL Update script so there are no security implications for sites who may have more restrictive upload policies. This will only apply to new sites.

Worth noting this is a better fit for J5 than J4.4 because the GD library support was only added in PHP 8.1 (although technically that doesn't stop people uploading the files themselves in J4.4 as web browser support already exists - it's just easier because they can be edited too) - https://php.watch/versions/8.1/gd-avif

Testing Instructions

Upload AVIF file. Before will be rejected and any files on the server won't be rendered. Afterwards they will be.

Does this close the following

#30666
#37669

Also see the changes made with #35752

@wilsonge You've changed the base.sql file for MySQL but not the one for PostgreSQL. This cannot be right.

[wilsonge]

#35752 is just for the image list field (I'm not aware of anywhere we use that in core). But people would have needed to upload those files by hand. This PR specifically addresses media manager.

Yes it will address #30666. However it will only address the AVIF part of #37669 (the original issue was a broader thing around document formats etc which obviously isn't covered here)

I have tested this item ✅ successfully on d0ec800

On 5.0.0-alpha4
you have to setup the file type and mime type in options

It works but doesn't produce a thumbnail in the media manager, and the instructions for adding .avif files are missing from the settings.

is it possible that you server doesn't support av1?

[brianteeman]

To test to see if your server supports avif see https://php.watch/versions/8.1/gd-avif

[wilsonge]

Also to check if you use patchtester you will need to manually update the parameters in media manager
