Bug 1998493 [wpt PR 55871] - Allow upgrade of renderBlockingStatus in Resource Timing for preloaded resources., a=testonly

Automatic update from web-platform-tests
Allow upgrade of renderBlockingStatus in Resource Timing for preloaded resources.

Note this only happens if the Resource Timing entry has not been emitted yet and makes the Resource Timing entry reflect Chrome's internal understanding of whether this is render blocking or not. Previously this was just stuck at the initial status.
