Subject: [PATCH] Upgrade/Install: track php extensions and image library
 support for WebP and AVIF.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add the loaded php extensions as well as whether the server's image libraries support WebP and AVIF image formats to the data payload sent during upgrade checks. Collecting this data with the WordPress.org API will help the project make more data driven decisions about feature support. Note that all data can still be filtered with the `core_version_check_query_args` filter for privacy reasons.

Props dd32, SergeyBiryukov, mikeschroder, pbiron. 
Fixes #48116.
