This patch refactors how we check for text formats when deciding how to handle resources, such that more text MIME types will be rendered in-browser, rather than downloaded. This change requires us to move more away from using the Gecko-Content-Viewers category in the category manager for this decision, as we need to handle an unlimited number of MIME types behind the scenes. Support for Gecko-Content-Viewers was left in for both the in-tree use for application/http-index-format and dynamically determining whether image/avif and image/jxl are supported, as well as for the message/rfc822 type used by Thunderbird.
