[13.x] Add HEIC and additional AVIF support

[riasvdv]

Summary

Illuminate\Image currently exposes AVIF output through Image::toAvif(), but rejects AVIF inputs before they reach Intervention Image. HEIC and HEIF inputs are rejected in the same way, and HEIC output is not exposed despite Intervention providing an encoder. This adds first-class AVIF input and HEIC input/output support.

• AVIF, HEIC, and HEIF inputs
• Image::toHeic()
• Image::optimize('heic')
• Image::optimize('heif'), normalized to HEIC output
• AVIF, HEIC, and HEIF support in the image validation rule

use Illuminate\Support\Facades\Image;

Image::fromUpload($request->file('photo'))
    ->usingImagick()
    ->cover(1200, 800)
    ->toAvif()
    ->quality(80)
    ->store('photos');

Image::fromPath(storage_path('app/photo.heic'))
    ->usingImagick()
    ->toHeic()
    ->quality(80)
    ->store('photos'); // stored with the canonical .heic extension

Also updates Image::extension() to recognize AVIF and HEIC/HEIF MIME aliases. HEIF output aliases are normalized to the canonical .heic extension and image/heic MIME type. HEIC processing requires an Imagick installation with HEIC codec support.
