[5.1] Proper support for avif/webp images

[dgrammatiko]

Pull Request for Issue # .

Summary of Changes

• add missing avif support in the Image class
• The resize plugin cannot create an image from string for AVIF files (someone needs to open an issue to php-src for this)
• both webp and avif cannot be supported for editing because browsers are inconsistent atm on the canvas.toDataURL()
  spec: toDataURL

Testing Instructions

• Either run npm I or use the package from the PR

• extract and upload the files Archive.zip

• Delete/rename the files

• Delete the files. Edit the Media Action plugin resize with some values (ie 800 and 500) and check that the images on upload are getting resized.

Can we remove the RTC. Turns out that PHP docs were wrong php/php-src#14010

Please test again with:

• Delete the files. Edit the Media Action plugin resize with some values (ie 800 and 500) and check that the images on upload are getting resized.

It was commented elsewhere that this PR would also resolve an issue with files named JPG as opposed to jpg.

Sorry to say this pr makes no difference

This pull request has been automatically rebased to 5.2-dev.

[dgrammatiko]

@HLeithner why did you moved this one to 5.2? This is a bug fix nothing new here...

[HLeithner]

I only had quick look and just classified it as feature since nobody else looked at it and added a label. If I'm wrong no problem can be changed back as long as nobody update the branch.

[dgrammatiko]

AVIF support was added with #41381 but George missed some parts. This PR just adds them, it doesn't have to wait for 6 months

Edit: actually it fixes the issue reported in the introductory PR: #41381 (comment) where you also responded: #41381 (comment)

[HLeithner]

switched back to 5.1 thanks
