Message:

Media: Avoid images with sizes=auto to be displayed downsized in supporting browsers.

Based on the user agent stylesheet rules outlined in ​https://html.spec.whatwg.org/multipage/rendering.html#img-contain-size, images that have sizes=auto while applying width: auto or width: fit-content would be constrained to only 300px width.

This changeset overrides said user agent stylesheet rule with a much larger constraint, to avoid the problem.

Additionally, it introduces a filter wp_img_tag_add_auto_sizes which can be used to opt out of the functionality, as an additional measure.

Props joemcgill, flixos90, dooperweb, SirLouen, azaozz, mukesh27, apermo.
Fixes #62413.
See #61847, #62345.
