This patch adds reporting the surface types used by the image frame in a bit mask (such if it is a CAPTURE including a DATA_SHARED, the mask will be 1 << CAPTURE | 1 << DATA_SHARED), as well as an estimated size included in the report as decoded-unknown for when we do not know if the surface is on the heap or the non-heap specifically. This is the default implementation for a SourceSurface as well, so we should no longer have the case where surfaces appear empty despite being in the cache. It also makes requests being validated as always notable for reporting purposes. Differential Revision: https://phabricator.services.mozilla.com/D61458 --HG-- extra : moz-landing-system : lando
